Squishable Alter Ego Plague Nurse Nymph.

 Plague Nymph! Nature spirit! Forest fairy! They have opinions about the breeze and the bees and the trees! 

Imagine an infinite number of alternate dimensions, sliced thin like salami and all layered together in a delicious sandwich of universes. In these parallel strata of time and space, the Squishables are very, very different. Squishable Alter Egos are all the Squishables that might have been (and almost certainly still are...somewhere).
