| Please note the following:
Poopy Butt, also known as Poop Butt and formerly known as Sh*tass, is a minor character who appeared in Jeffy's Dog! as Jeffy's new pet to replace Melvin (Pee Pee Suck II) for getting lost during hide and seek. Sh*tass is known for randomly pooping on the couch. He is paralyzed from the neck down, which is why Rosalina chose him: so he can't run away from Jeffy.
When Jeffy started having vision problems, Brooklyn Guy was called over to check on him. However, he was under the belief that he was called over to euthanize Sh*tass and came to the house with a syringe. After learning that he was not asked to euthanize Sh*tass, he disposed of the syringe by sticking it into Sh*tass' abdomen, so he died anyway. Jeffy did not notice that Sh*tass was deceased as he moved him off the couch.
He later appears alive in Jeffy's New Shoes!, where he chewed up Jeffy's shoes.
He then died for real in Jeffy's Bad Dog! after eating Jeffy's chocolate cake & been revived by Craig the Devil. Only thing is he is now evil, immortal, & able to move, until Jeffy dropped a bowling ball on him which paralyzed him again. He got his name from Jeffy's tendency to give his pets vulgar names. However, as of Jeffy's Pokemon Card!, he's called Poopy Butt due to YouTube's Community Guidelines.
- Poopy Butt surprisngly is Chilly's favorite character.
- Logan changed the name from Sh*tass to Poopy Butt in order to maintain the channel's family-friendly streak in early 2018. Even after SML videos started using profanity again, the name Poopy Butt remained.
- He has not appeared in 2019 and has yet appeared in 2020. Because of this, it is unknown if he still is evil and will continue biting Jeffy.
- However, Tito is no longer a part of the SML Cast, so It's possible Poopy Butt won't be in videos anymore. That is, unless Logan finds a new voice actor for him (if he is brought back as a character).
- Logan stated in Lance's BTS video that Poopy Butt's left eye broke from bowling ball scene in Jeffy's Bad Dog! along with his missing teeth and eyebrows.
