I haven't decided what I want to do with this character, but I decided years ago that he exists in this form in my story universe somewhere, and I randomly felt compelled to do these doodles of him. Also, here's some additional info that isn't in the little notes:

'Morton Q Mortimer' is the name he gives when asked, but it may not be his actual name, and it's unknown what type of creature he is. He can be any size as well as any shape, including looking like either gender of regular anthro. He's physically genderless, but prefers 'he' to 'it' or 'they'. He may have come from another dimension, as he has the ability to travel to any dimension at will (excluding the Dimension of Lost Socks, as he is that dimension in a sense), as well as teleport around within a dimension. He has at least some reality-warping ability, though the full extent of what he can do with it is unknown.

He can widen his mouth to swallow objects/people of any size (including things larger than his current shape), and the stripy patch on his belly is infinitely stretchy. His torso is completely hollow with no internal organs, and anything he swallows will remain there for a short time as though being digested (though the people/objects will not be harmed) before being transported to the Dimension of Lost Socks. Socks are the most commonly-swallowed object (hence the name), but many other things also end up there (including many pillows and other cushion-type objects, making it actually a rather comfy place to spend time in). He can also return people/objects that are either in the Dimension of Lost Socks or still inside him by spitting them out.

His morality and motives are unclear and confusing, as he seems to follow a different logic than everyone else. He doesn't seem to be outright malicious, at least.
