Although not pictured, his pajamas have snaps on the butt!

Reaction to spicy carrots

Lemongrab's entrance into the castle, with a beady-eyed Lemon Horse.

Lemongrab met by confused reactions from other candy people.

He seems rather disturbed when he sees candy people smacking each other with pillows.

Lemongrab's original design, which included eyebrows, nipples, a gap-tooth, and a belly-button. Note the look of sheer horror on Princess Bubblegum's face.

The earl demonstrates the policy of a logical, benevolent ruler.

Unused storyboard illustrating the earl as being unintentionally frightening

Too Young promo art by the episode's storyboarders, Jesse Moynihan and Tom Herpich, depicting the Earl of Lemongrab surrounded by many unacceptable things.

Clean this place up or 3 Hours Dungeon

Newborn, unconscious LG, seconds before his very first screaming fit.

It's a boy!

Doing what most newborns do; freaking out and screaming. (And he's a bit pudgy in the midsection!)

The sheer terror of LG's first moments resulted in this.

"THREE HOURS DUNGEON!" The earl demonstrating his impeccable people skills.

LG taking a nap after the long trip. He actually looks calm for once.

YOU REALLY SMELL LIKE DOG BUNS

He seems to dislike Pepbut a LITTLE less than everyone else, probably because he makes good food.

"Sooo WHICH one of you WAS it?! Who did THE THING?!"

"Hey, man- calm down!"

Whether he's genuinely in a good mood, or just confused, is up to speculation.

Lemongrab laughing and unintentionally creeping everyone out (moving GIF image, click to view)

Projectile vomiting all over Peppermint Butler! Not fun for either party.

This scene is removed in some dubs.

As is this one.

Extremely good jump, or maybe just a weird camera angle.

It's exactly what it looks like.

Muttering to himself sadly, on his way back to Lemongrab

Finn with a face uncannily similar to the Earl's.

I AM NOT GREASE!

THIS IS UNACCEPTABUUUUUUUUUUUUU—

"Yes."

Put you in my oven!

It's gross!

I think I'll use mah sound sword again

This is his thinking face!

Awww.

Tiny Lemongrab!
