It was "Jonah", BTW.
And it's Larry the Cucumber, and his superhero character is "Larry Boy", and is quite hilarious (with the Batman take offs and all).
Yeah, Jonah, sorry. The kids had it on in the back of the van and all I coould make oyt was Maccabites this and Somewhozits that, and I made sure the tape got left back at Grandma's.
My kids watch Little Bear, Care Bears, Arthur, etc., and they all have a very positive message but manage to remain secular rather than supernatural. There is much more uplifying kid's programming on now than when I was growing up to be sure.
