Twinjas

Twinjas is a television show on the Dingo Channel, which is said to be about the adventures of twin ninjas. It is briefly mentioned in iToe Fat Cakes when Carly is flipping through channels while taking a bath. She doesn't seem to very enthused to watch it, so she changes the channel to watch The Vintage Network.

Twinjas is assumed to be a parody of Twitches and Kickin' It. It could also be a parody of Teenage Mutant Ninja Turtles.
