Jigg

This character is technically a closed species character (a Jellydog), but I've done nothing with him since getting him and I don't think the owner of the species is active with the species anymore, so I'm integrating this character into my original fantasy world. 

Jig was originally an ordinary dog but later he bonded with Twi the dragon.  Upon bonding with her he gained her ability to change the shape of his body around (almost like his body is made of jelly).
