Well, all the GenJyuken animals were mythological beasts based on the animals of the oriental Zodiac. The ShiGenShou, specifically, were based on the four guardian spirits of Kyoto. Since a turtle is not considered a mystical animal, the creators had to go a different route.
The story of Genbu also included a snake that was wrapped around it, so I guess they chose to highlight the snake aspect and use the mythological animal based on a snake (i.e. Basilisk). He looks like the turtle only to coincide with the "four guardians legend". Hope that clears things up for you.
I think Bomper could use a new paint job.
