Professor Neptune Greene was a turtle who turned into a frog. frog who was in the Baby Einstein series. He was scared away by vincent in Baby Van Gogh, where he popped his balls. he was seen in a pond, wearing a floatie, and watching butterflies and dragonflies dart and pass right by him. This poem from Vincent Van Gogh is recited.
Green slithers in to make me cool.
I'm floating in a still, wet pool
With butterflies that dart and pass,
Surrounded by the glistening grass.
