Special abilities for primordials
A pet form, can get several animations, interacting with objects or doing whatever things. Each such animation can get one special ability assigned to it, known only by its owner. The abilitiy must make sense with that particular animation and the pet. These abilities might emerge in pet to pet encounters..wait..what? .. nevermind that now :D, consider it a keepsake, a memory of that animation. Animations and special abilities do not influence how the primordial grows, only feeding, owner and parents does that.
