The Amalgamates usually found in Alphys' lab during a True Pacifist Run in Undertale have made a name for themselves in ArtTale. Since they still don't leave the Lab, they've re-created it, MS Paint style!
The Amalgamates look a bit rougher than before, and their feet/paws are colored (representing them stepping in paint).
Edogeny is very similar to the original, but the appearance is changed in some ways. The white goop is now replaced with black ink, and the seven paws of the Edogeny are now covered in seven different colors representing the rainbow. The most noticeable difference is the orifice on Edogeny's face. Now spouting out purple paint.
