Tess

Pixel Tess is a Whimsicott who is also of the unnamed Pixel character type described in Entry: A Sinking Feeling. She’s vorish because of what she can do with her character type ability, but is also kind of a hoarder since the space inside her cotton is unlimited and retrieving things from it is easy.

Her cotton is just that, however, and liquids will seep into it quite easily and some things can stick to it as well. This will ruin both the cotton itself and whatever it's stuck to, the latter only for other characters as she doesn't mind eating some of it, although the connection that allows her to directly swallow things from her cotton isn't that. Said connection is simply a connection between all of her cotton anywhere to the same pocket dimension, and she has some on what would be her wrists, meaning she can put it in her mouth and use the connection to swallow things that are stuck in her cotton. Additionally, the deeper something that seeps into her cotton is when it does, the harder it is for it to be cleaned, and she likes keeping her cotton clean so anything that ends up inside it isn’t affected by something that’s seeped into it.

If Tess is being digested, her cotton is gradually lost and cotton from her pocket dimension will come up to replace it. This can lead to the loss of items but can also eventually lead to some of the ruined cotton being destroyed, which she likes happening but it is made moot by the amount of items that are generally lost to get to that point and the fact that that cotton can be so far down that the rest of her gets digested before it gets that far.

From some potentially non-canon scenarios, it has been revealed that Tess doesn't like violence, owing to the compassion demonstrated in a different scenario where she encountered a non-Pixel character and gave them a white Pixel Glove so that the two can keep contact, most importantly because that's how she'll know when they need to be let out.
