If we (perhaps somewhat improperly) define "animal" a mobile,

All photosynthetic orgamisms I know of are either immobile plants or

Because a photosynthetic animal could never obtain enough energy to
survive unless it was spread so thin that it would immediately dry out
in the noon-day sun. Plants aren't as stupid as they look.

some of these issues conquered; I think it was titled "Gotta Sing,
Gotta Dance". Geek, Geek! - JAH]
