[hisses]
[growls]
[giggling]
[Arthur] Hey, Mina, look what I found in the basement.
It's a box of your old stuff.
Aw, Dad, this stuff is embarrassing.
"World's Best Tromboner."
[imitates sad trombone]
Check out this old photo album.
Here you are with your imaginary friend. [chuckles]
Remember Hamburger Cheese?
Aw... Hamburger Cheese.
He was my best friend before you guys came along.
Best imaginary friend.
It's been so long, I forgot all about him.
Hamburger Cheese was a gentleman prankster.
[sighs] I remember we loved pulling pranks on Dad.
Like when we replaced his toothpaste with super-hot horseradish.
Or how about when we helped him with the backyard sprinklers?
The old "plastic wrap over the doorway" gag.
Taking Dad to the emergency room.
[sighs] Yep, we used to do everything together.
He was my best friend in the whole world.
Yeesh, Mina was a lonely child.
Look, Mina, here's some video from your fifth birthday.
Alone? Again?
Uh, I mean with Hamburger Cheese?
[chuckles] That was the year I got you guys as pets.
Ah, the memories.
Oh, Hamburger Cheese, I wonder where you could be.
[yawns]
[screaming]
[humming]
Huh? [yelling]
[gibbering]
[groaning]
All right, where is he? Where's Bunnicula? Did he prank you too?
-Meh. -Ugh.
[gibbering angrily]
You. What's the matter with you?
Pulling pranks like that?
Horseradish on my toothbrush? Really?
I could have gotten hot tonsillitis.
That's a real thing I just made up.
And look at Harold. You made him damp, Bunnicula. Damp!
[gibbering]
Oh, no, no, no.
This isn't my fault.
You're the mischievous one.
Oh, man, what a day!
It's like everything's going my way.
And to top it all off, this $50 bill just flew into my pocket.
Somebody must be looking out for me.
How was your day?
Great!
All right, something weird's going on here.
Weirder than usual.
I've taken the liberty of creating a flow chart
to find exactly what it is that's haunting us
every time something strange happens.
Let's see. Ghosts, no.
Demons? No.
Swamp magic? No.
Bikini lobster?
[grunts] This is useless.
This menace defies all categories.
You know how I get when things don't fit into categories.
Guys, the cause of this is right over there.
Don't you see him? [laughing]
He's laughing at us.
Uh, you talking about the door?
No, it's Mina's imaginary friend, Hamburger Cheese.
You can't see him? He's got a beak like an eagle
and big round eyes with four frog legs, four flippers, four thighs,
an old navy pea coat and a stovepipe hat.
There's only one fellow that looks like that.
You won't see his equal from here to Belize.
Your old pal, the one they call Hamburger Cheese.
[both blowing raspberry, then laughing]
-[door slams] -[both gasp]
Aw, he went away.
-I'm going to go sit in that sunbeam. -Whoa, whoa, whoa, whoa, whoa.
-You think he's right? -[gibbering]
Well, why is it that Harold can see him and we can't?
Is he some kind of a genius?
[gasps]
[laughs] I forgot to breathe.
[gasps] That's it. Harold thinks like a child.
That's how Mina was able to see Hamburger Cheese when she was young.
Bunnicula, to see this thing we have to get childish, simple, silly.
To stop this creature, we have to go full Harold.
[fly buzzing]
Hey, buddy, what's going on in your world?
-What are we looking at here? -Watching for Inflatable Bob.
Uh, sure. Okay, what does he look like?
I don't know. Never seen him.
What exactly are we gonna--?
[snoring]
[barking]
You guys gonna get some of this tasty beverage?
[slurping]
Ah. Huh?
-[Chester groaning] -[Bunnicula] Ugh!
Look, guys, a fleet of Spanish galleons.
Uh...
Hmm.
Wow!
[gibbering]
Bunnicula, you did it.
Now, jump on your sky dragon, and let's have some fun. Woo-hoo.
Sky dragons? What?
-Woo-hoo. -Woo-hoo.
-Yeah! -Yeah.
[laughing]
[gibbering]
Yeah, and you were like-- And I was all... [exclaims]
[both laughing]
But how do you do it?
How do you see Hamburger Cheese?
Well, Chester, sometimes I use my imagination goggles.
Like this. Oh... [laughing]
[laughing]
See? [laughing]
[gasps]
-[growls] -There he goes.
Couldn't you have chased him into a less creepy location?
Mina's old stuff is all over the place.
[thud]
Hmm.
[Harold] Hey, our faces are crossed out.
[Chester scoffs] For you, that's an improvement.
[Harold] What does it say on the back?
[Chester] It must have been written by Hamburger Cheese.
"Mina remembered me, that's why I've returned."
-What? -Hamburger Cheese is saying
because Mina remembered him, he's come back.
I know.
"But her three animal friends, her friendships unearned."
-That's us. -I know!
"Rather than prank them and be cruel,
I challenge the bunny to an imagination duel."
Oh, my gosh.
He just challenged Bunnicula to an imagination duel.
-[gibbering] -We know!
And now we're trapped.
Hi! Ow!
[growls]
[yells]
Hi-yah!
[exclaiming, then panting]
[yells]
[groans]
Bunnicula's powers, they're not working.
Bunnicula, remember, Hamburger Cheese is imaginary.
You have to use your imagination.
[echoing] Imagination.
Imagination.
Your eyes can see me, you are no fool.
We'll see if you're worthy of Mina's friendship
in this imagination duel.
-Huh? -That sounded better in my head.
[gasps]
What's he doing with that old roll of wrapping paper?
He's... believing.
Aha!
A fiery sword? Ooh, that's imaginative, bunny.
But swordplay with me? [chuckles]
Now, that's pretty funny.
Uh-oh!
Oh, oh! The brutality.
-Oh, I can't watch. -What? Where?
[yells]
[groaning]
Hamburger Cheese is too powerful.
This could be the end of Bunnicula.
I don't understand.
There's nothing there.
That's the spirit, Chester.
What you're saying is, "There is nothing there."
To be afraid of.
It's all in your imagination, Bunnicula.
You have to imagine bigger.
Hmm... [gibbering, then growls]
-Uh, what just happened? -Oh, there he goes!
[exclaims]
[Harold] Now, we'll see this epic duel play out.
Yes! Bunnicula's rocket-powered carrot is kicking his butt!
His what?
[grunts]
Oh, no. Now Hamburger Cheese is on top of a giant two-headed lizard
that shoots lasers from its eye.
Sic them, boys!
[roaring]
-Where? -Ooh, but Bunnicula's coming back.
He's piloting a giant robot Abraham Lincoln.
[laughs] This battle is so epic!
This is definitely Bunnicula's greatest fight.
Uh...
[exclaiming] Boom!
Yeah, we did it! Bunnicula saved the day.
Uh... Yay?
Yay!
[groans] It seems I've met my match.
I've lost the duel for Mina's friendship.
Alas, there's no going back.
Without a friend to remember me, I shall fade away.
Uh, guys, what are we looking at?
Mina, your memories, your imagination kept me alive.
If only there were a lonely, pathetic soul to help me survive and thrive.
Hmm... Who do we know that's lonely and pathetic?
[all gasp]
[laughs] Have some more nachos.
[laughs]
Oh, this is great.
Good buddies sharing a special moment.
Only in America. [laughs]
Uh, who is he talking to?
[gibbering]
[sighs]
