this question is very important, was it live action, animated, or puppeted
also another question that comes to mind when reading wiki's pbs history, where were
you a kid at, because programming can change just based on that
do you hail from the u.s., canada, england, etc... that could also help
I can give you some suggestions that I have found from pbs
Puzzle Place
Wimzie's House
Polka Dot Door
now I had not looked though the plots that much, but just see if one of them rings a bell
two things come to mind when I think about this. 1) have you ever heard of the elephant show
it had a spider with many legs and had tennis shoes on it's feet.
2) this also reminds me of beverly clearly and judy blume books if that helps to ring a bell
i'll keep an eye out for your next comment on this post and good luck on your search
