Another one I have is his species. Since he is a slime blob, he would be related to Gluto's. There are three different species, each which uses devices that help with their physical form.
I think sploot doesn't need that gravity disc. The device inside him is fine.
Maybe in Ben 10k He might be slightly bigger.
That sounds like a cool idea.
Improving this, since in the future timeline any remains of a villain are stored into Sector 15-D. One Student was helping a friend of his (who is a polymorph) recover from a strange disease, preventing him from shapeshifting and maintaining his physical appearance. When he takes a sample from one of Sector 15's Unstable DNA, the Polymorph winds up becoming Sploot.
