Phil's species

"Phil's species" refers to an unnamed alien species from the Crab Nebula.

Biology
They have the physical appearance of a green-colored human mouth with sharp teeth, and what appear to be eyestalks. Considering they come from the "Crab Nebula", it can be inferred they are crustaceans. Apparently, their way of saying "yes" (at least according to a disembodied floating mouth) is sprouting fins, screaming, and exploding. They also seem to be able to regenerate after exploding, as shown by one of Phil's eyestalks sprouting out of the goo he exploded into.
