Puffy Fluffy is a character in the animated TV series SpongeBob Squarepants. He only appeared in the infamous episode "A Pal for Gary" as the main antagonist.
He is a nudibranch (although not resembling an actual nudibranch at all). He first appears as a small, chubby green fish with a goofy expression and razor sharp teeth, but eventually evolves into a huge lamprey-like beast with several sucker-like tongues inside his mouth.
He was voiced by Dee Bradley Baker.
Puffy Fluffy was bought by SpongeBob, so that Gary would not be lonely while he was at work, even though Gary was perfectly fine with staying home alone as he could see television on his own. However, Puffy Fluffy turned out to be a ferocious monster and attacked Gary several times (while SpongeBob was oblivious to the entire situation).
SpongeBob never notices and blames Gary for the destruction of his house, which was really caused by Puffy Fluffy. Puffy Fluffy sheds his skin during the night and turns into his fully grown monstrous form, resulting in Gary battling him throughout the house the entire night.
When SpongeBob starts to scold Gary, ignoring the fact that Puffy Fluffy is now trying to devour the snail with his tongues, the monster decides to eat him instead. Gary saves his owner's life by tangling up Puffy Fluffy's extra mouths with his own leash, preventing him from eating and sending the monster running out of the house in a sobbing panic.
Even so, SpongeBob still scolds Gary for chasing Puffy Fluffy away, even though Gary ended up saving his life and the house.
- Without a doubt, Puffy Fluffy is considered to be one of the most hated characters on the whole show. This is partially because his episode was popularly loathed for flanderizing SpongeBob's characterization at his worst, given his infamous obliviousness in not realizing the threat that Puffy Fluffy posed for him and Gary.
- Nudibranches, Puffy Fluffy's species, are actually sea slugs, which his monster formation resembles a bit.
