A group of kids (puppets) from diverse backgrounds and cultures come together at "The Puzzle Place" to hang-out, tell stories, sing songs and hold celebrations. Along the way they learn important Life Lessons about getting along, communicating, and how to be a friend. There is usually also a sub-plot centering around the club's sibling-like dog and cat, Nuzzle and Sizzle.
Back when I was a late-elementary schooler and off from school, I'd often watch this show. I was probably a touch older than the intended audience and I found some of the characters and storylines annoying, but as far as TV viewing went, I didn't have too many choices then.
I'm hazy on the details of the episodes; I just remember one where Kiki entered a chili contest, another where Julie brought in moon cakes for Chinese New Year, and one where Leon hid under a desk because of his fear of thunderstorms. They had a greenhouse and a TV where they watched videos and had conversations with people. Also, the dog and cat were always getting up to mischief in the basement.
