ChalkZone/Nightmare Fuel

As charming and wacky as it is, this show has more moments than you can count.

• Snap, Penny and Rudy singing to a giant, sentient piece of cake as they devour her, little by little.
• A chalk-targeting vaccum that sucks up about 99% of Chalkzone before it's stopped.
• In "Howdy Rudy", the titular character (a sentient Rudy chalk puppet) is about to return to Chalkzone when a dog that he has befriended arrives, and begins to lick him in happiness. You can guess what happens.
• Rudy being forced to have a dirty diaper put around his head.
• The Spine Slurper. it is said to literally slurp out someone's spin. We even see a victim of this working for a cruel king, though thankfully we don't see any live slurpings.
