Tokka began life as a piece of action figure concept art submitted to Playmates by Steve Murphy and Steve Bissette:

"Terrorpin the Terrible with his sidekick, Snappy Warhol!" While the idea was initially rejected, Terrorpin was reworked into Tokka for the 1991 film, "TMNT II: Secret of the Ooze" while Snappy Warhol did not survive the process. On the bright side, he was replaced by Rahzar:

A mutant snapping turtle would appear in the Mirage comics only nine months after the release of "TMNT II", in Turtle Soup (Vol. 2) #2.

In 1993, Tokka would make a one-shot appearance in the Fred Wolf animated series, in the episode "Dirk Savage, Mutant Hunter":

And then Tokka would promptly cease to exist until he was revived for a cameo appearance in the 2009 TV movie "Turtles Forever", making his way into the 4Kids animated series:

And thus ends our tour of Tokka. Exit on your left. Have a nice day.
