I've been working on this since June, and it's been tested at least 3 times (still waiting to hear back from 2) and seems to work good.

Hutts is a shapeshifter, usually via melting into a purple puddle of goo and reforming from that, may also spin around and vanish into thin air and re-appear somewhere else. Known to pull objects from nowhere, usually has the bound weapon summoning effect from Skyrim. Sometimes opens the lid of an invisible container and pulls something from there. Rarely uses traditional hammerspace but it is an option.

Can sprout wings as seen in previous references.
Sometimes reforms himself with 3 toes instead of 4. If staying gelatinous may not bother with toes at all.
Hasn't had claws since 2013. Recently decided to do away with paw pads as I noticed I was making an effort to avoid drawing them (as evidenced by my Info Tab.

His usual outfit can be seen Here.
Still working out how to layout the Lucario form reference. Will link that here when it's done.
