Poopet is a YouTuber alter ego belonging to Dawko, technically his first appearance was on a St. Jude's charity live stream in either 2015 or 2016 when Dawko dressed up as the Marionette from FNAF.

Since then he's appeared in FNAF Freddy in Space 2, he has a Makeship plushie and Youtooz figurine, and he was teased to be in Manic n Panic before the show was CANCELED.

Also he glows in the dark so that's cool.

Since there's not much canon information about Poopet I'm gonna yap about my headcanons!!

In my Dawko Egos AU, they are all siblings living in a house together and Poopet (Poko) is the oldest. Also I refer to Poko as They/Them rather than He/Him.

Poko being the oldest, they have a lot of pressure on them especially since their dad (Lewis) is neglectful but they love their siblings and would do anything for them. They've got a naturally calming and gentle aura that soothes anyone near them.

They are half-puppet half-human and have puppet jointed arms, they enjoy crochet, sewing, and baking primarily. They are always giving little gifts to their siblings...

Darko is like their twin except they're two years apart in age but Darko is also half-puppet and the two of them share a bedroom together which is the FNAF 2 gift box.

Darko lowkey hated Poko at first but they've grown very close over the years.

Nightko (Night Guard Dawko) and Poko are also very close as Nightko is the second oldest and in later years relies on Poko for comfort.

Guys I love Poko.
