Sam Snow.
Kit Casey.
All aboard the Monsoon Express!
Next stop, dry ground!
Ah, we've reached full speed. Watch the controls, would ya?
You got it, Chief.
Hey, watch it, pal.
Sorry. Excuse me. I didn't mean to--
Sweet slippery slugs!
-Chief!
-Got it, Bill? -Got it, Jill.
-Let's send to CLADE. -Sam and Kit will know what to do.
-One!
-Two!
-Three!
-Four! Five hidden paw prints.
Ha!
This training exercise was a breeze.
Not bad.
-But you missed a few. -Really? Where?
Here.
And here.
See, Kit?
That's why you're the animal expert, and I'm the master detective.
-I never miss a thing.
Sam. Ya missed somethin'.
The CLADE crest!
The Director must have a new Creature Case for us!
-Better not keep her waiting.
Huh?
Huh.
Forty-two seconds. Not bad, agents.
-Director Scratch, we came as soon as we--
Agents, there's a major mystery on the Monsoon Express.
Monsoon Express? What in the woolly world is that?
-The Monsoon Express is a train.
When the jungle gets too rainy and wet,
the Monsoon Express takes critters up to higher ground where it's dry.
But earlier today, the train's engineer was attacked.
The Mice Squad just sent us these photos.
Hmm. Any idea who did it?
That's where you two come in.
Your mission is to figure out who attacked the engineer.
Oo, we've never solved a mystery on a train before.
This could be our biggest Creature Case yet.
Stinkwells will help you gear up. Good luck.
And remember.
CLADE is counting on you!
-Can I have one of these? -No.
-Hello, Sam. -Hello, Kit.
Hey, Stinkwells.
What are you needing today?
A Bat Jammer?
A Turtle Tracker?
Orangutan Tickler?
We're solving a mystery on the Monsoon Express train,
but it already left the station, so…
Oh, we have just the thing for you.
These Glider Packs will help you fly aboard the train.
Whoa!
They're perfect!
But…
Are they supposed to smell like that?
Oopsie.
-Thanks, Stinkwells.
Goodbye, Sam.
-Goodbye, Kit.
R.O.N., set course for the Monsoon Express.
Prepare for blastoff.
Now approaching destination biome,
Asian Jungle.
Thanks, R.O.N.
There's the Monsoon Express.
Ever skydive onto a moving train in a tropical downpour?
-Nope. -Neither have I.
R.O.N., open the hatch.
Now, when the train is directly below us, we'll ju--
Race ya!
Woo-hoo!
Wee!
Whoa!
Activate Glider Packs!
Oh yeah.
Whoa…
Oh! Careful, Sam! You'll miss the train!
Thanks, Kit! I owe you one!
But I told you. I never miss a thing!
We'll get in through here.
-Ha-ha!
Whoa.
Gotcha!
Phew!
Thanks, Sam. Now we're even.
Afternoon, folks. Agent Sam Snow…
And Agent Kit Casey.
Animal Detectives.
Detectives?
We're from CLADE, and we're here to solve a mystery, little buddy.
Okay. Do you know where we can find the engineer?
The engineer is right over there.
I mean, I think that's her. I wouldn't know.
Why would I know?
-There she is! -Can you tell us what happened, ma'am?
Nope. Those are definitely not words.
Oh, you gotta help her!
I'm just the assistant engineer!
I don't know how to drive this thing myself.
We're on it.
Sam, check this out.
A clue!
Huh? It looks more like a hat.
It is a hat. And a clue.
But it's not my hat.
-Or the engineer's.
Exactly. Whoever attacked the engineer probably left it behind.
Hmm. Interesting pattern.
Ah-ha!
Any idea what this is, Kit?
Looks like a scale.
-A reptile scale.
Like from a lizard.
Or a snake.
A snake… Hmm…
Just as I suspected. A snakebite.
-How can you tell? -There are two little bite marks.
The kind left behind by something with two big fangs.
Like a snake.
A snake, huh?
Hey, don't look at me.
I may have fangs,
but I'm just a completely not dangerous egg-eating snake.
Nope. No venom at all. Huh…
It's true.
Some snakes have venom, and when they bite, it makes you sick.
Like this.
This egg-eating snake here doesn't have venom.
But the snake that bit the engineer definitely did.
If we can find them, we can turn some of their venom into medicine!
You can?
Yep.
A lot of snake venom made her sick,
but a teeny little bit, mixed in with my special ingredients,
will make her feel all better again.
Solid plan.
Just one question. How do we get the snake venom?
With this. A Venom Extractor.
Snake bites this here. Venom drips into here.
-Never leave home without one. -Now all we have to do is find that snake.
Clu-Bots, check this train for snakes.
Eh? Eh? Uh?
-Whoa.
According to the Clu-Bots, there are 32 snakes on board.
Ah, you'll never find the one who bit the chief.
Oh yes, we will.
Check it out.
Only half of these snakes are venomous.
And only four have enough venom to make the engineer sick.
The Big Four!
Afraid so.
Uh, the big who?
The Big Four are the four most dangerous snakes in these parts.
The Chain Snake, the Common Krait, the Indian Cobra,
and the Saw-Scaled Viper.
There's one of each on this train. And they're all venomous.
Hmm…
So one of these Big Four snakes must have bit our engineer friend here.
Bingo.
But don't you worry.
We're gonna find that sneaky snake and make some medicine to fix ya up.
-Huh?
Hurry!
We'll be reaching dry ground soon,
and she's the only one who knows how to stop the train!
And if the train can't stop, we'll crash!
Crash? Oh no!
We're gonna crash?
Oh no!
Stay calm, everyone.
We're on the case.
Time to find that snake.
Okay, Sam, we've gotta find this snake. Fast!
First on our list of suspects, the Chain Snake.
That's him over there.
And boy, is he hungry.
Remember, Sam, all of these snakes are fanged and dangerous.
Excuse me, sir. Agent Sam Snow.
We'd like to ask you about-- Huh?
Sam, look out!
-Uh… -Whoa.
Spicy.
Excuse me. Still digesting last week's dinner.
Looks like you'll be working on that for a while.
Food stays in a snake's stomach for a long time.
I see.
I don't suppose you know who bit the engineer?
Who bit who now?
The engineer was bitten by a venomous snake,
and now she can't drive the train.
You mean nobody's driving the train?!
We gotta do something! Okay.
-I'm stuck! -Stay calm, everyone.
If he'd bitten the engineer, he wouldn't have been able to escape.
Yeah. Not with that big belly of his.
I already told you. It's from last week's dinner.
Well, we can cross him off the list.
One snake down,
three more to go.
Here. Let me help you.
Thanks.
Next up, the Common Krait.
Shh!
This is the sleeping car.
Sorry.
This suspect is very dangerous and very--
-Tired?
-We may have found our suspect, Kit. -Sam…
I bet she tired herself out attacking the engineer.
-Sam. -Now we just have to wake her up and--
Sam! Common Kraits are nocturnal.
They sleep all day and only wake up at night.
And the engineer was bitten in the daytime,
when this snake was fast asleep.
-Uh…
Yep. She didn't bite anybody today.
Better cross her off the list.
Two snakes left.
The third suspect should be in here.
The Indian Cobra.
There she is.
Excuse me.
Hmph. Hmph.
And she looks like a mean one.
Ew! Pink scale polish? How vulgar.
Excuse us, ma'am…
What do you want?
Uh, my partner and I just need to ask you a few questions about--
No questions, pussycat.
Shoo!
Ma'am, earlier today, we--
I said no questions!
Ha!
Careful. Cobras flare out their neck hoods when they feel threatened and might bite.
And her neck hood's a-flarin'.
Neck hood?
Huh…
Sorry to bother you, ma'am. Have a nice trip.
Hmph.
Oo, tail warmers?
Sam, she was acting pretty guilty. We're just gonna walk away?
We sure are, Kit.
She has a neck hood that flares. But check out the Mice Squad's photo.
The snake who bit the engineer doesn't have a hood!
So the cobra wasn't the biter!
See? I never miss a thing.
Now we know it wasn't the Chain Snake, the Common Krait, or the Indian Cobra.
Which means there's only one of the Big Four snakes left.
The Saw-Scaled Viper.
Exactly. The Saw-Scaled Viper must have bitten the engineer.
-But where are they?
Agents, I don't mean to rush your detective work,
but can you please hurry up?
Don't worry. We've almost cracked the case wide open.
Well, this train's gonna crack wide open if the chief can't stop it soon.
We're about to crash!
Don't get your tail twisted. We're on it.
Okay. We know it was the Saw-Scaled Viper,
but now we only have minutes to find him.
Whoops! Excuse me.
Totally not venomous egg-eating snake coming through.
Whiskers, that's it! We just found him!
The egg-eating snake we met when we first arrived? But, Sam…
-Whuh-oh!
Stop that snake!
Watch out!
There he goes!
-Ah! What was that?
Oops. Sorry.
Shh!
Oo…
Whoa.
Shh!
Hey, that's my hat!
Hey! Watch it!
Ha! Nowhere left to slither now, Viper.
Listen, I told you before, huh?
I'm just an egg-eating snake. I'm not dangerous.
Nice try, but you're actually a venomous Saw-Scaled Viper!
You sure, Sam?
Egg-eating snakes and vipers look a lot alike. They're hard to tell apart.
Check it out, Kit.
The pattern on his scales looks just like the pattern on the hat we found.
Hey, my hat!
I mean…
That don't prove nothing.
And remember the snake scale we found?
Well, guess who has a bald spot on his head?
Oh… That's embarrassing.
Well, ain't that something. He's a Saw-Scaled Viper all right.
And he's the biter. He tricked us.
Okay, so I'm a viper!
But I didn't mean to bite the engineer. She startled me and I snapped!
It's just my nature.
Easy now. We just need a little of your venom.
My venom? Why?
I can use it to make medicine for the engineer.
So she can stop this train before it crashes!
Huh.
You want my venom?
Come and get it!
-Oh no, you don't!
You're all venomed out, Viper. At least for a while.
-Nice work, Kit. -Thanks.
Come on. Let's get back to the engineer.
We don't have much time!
I hope they hurry. We're gonna crash!
Oops. Is this mic on?
Hurry!
Just need a teensy bit of viper venom, my secret blend of herbs and spices…
Hurry, Kit!
There! The perfect snakebite medicine.
-It's working! -She's waking up!
Good morning.
Chief, I know you just woke up,
but you gotta stop the train before we crash!
Sweet slippery slugs!
I gotta stop the train!
Look out!
Shew!
-Yay! -All right!
Yeah!
Ladies and gentlemen, we've reached dry ground!
What a relief.
-Yay! -Here we are.
I had the weirdest dream.
I was attacked by a venomous snake wearing a tutu.
That was no dream.
Well, except for the tutu part.
-Thanks for all your help today! -Don't mention it, Chief.
Well, Kit, that's another Creature Case…
Closed!
Nice work, agents.
Now, come on back to CLADE for your next assignment.
We're on our way, Director Scratch.
-Uh, Sam? -Yes, Kit?
Did you forget to put R.O.N. on autopilot before we jumped out?
'Course I didn't forget. I never miss a thing. Why?
It kinda looks like you forgot.
Uh-oh.
Never miss a thing, huh?
-R.O.N.! -Hey, R.O.N.!
-Over here! Hey, R.O.N.! This way! -R.O.N.! Over here! R.O.N.!
Mice Squad Fact File.
Status?
Update. The Big Four Snakes.
The Big Four are the Chain Snake, the Common Krait, the Indian Cobra,
and the Saw-Scaled Viper.
They're four of the most dangerous snakes in Asia!
All four snakes have venom.
Which can make you pretty sick if they bite you.
They don't ride trains,
but when it rains, they do head for dry ground.
So watch out for the Big Four.
