Captain Infinity is the mascot of KCET Kids, She orginally was on PBS Kids as she used to fly around and send happy birthdays to kids, Today all she does is let you spell the word and answer math problems,
As of now, Captain Infinity is still on KCET but only on breaks!! Theres also an variant of the Use Your Imagination Song With Her Breaking The Fourth Wall. And the idents of her used the Jetpack ID and the Planet KCET ID. The Captain Infinity Theatre opening and closed was changed in early 2011 but now you can see her on TV still.
