It resembles Nightmare Goofy from FNATI NBD.
By the way the creator never shows it's legs.
It's starting location Edit
It's behavior Edit
Unknown but there is a animation jumpscare of it inside the project.
The time it is active on Edit
It has no gender what so ever
It is a human corpse shaped like a cactus
His only full body visible would have to be his arms,chest,head,bone parts because it's unknown his legs are not shown a lot
In his jumpscare he is more fatter and dark red that's because it is the old design
