I'm trying to remember the name of a particular children's television show that aired in the '80s. I'm pretty sure it aired on PBS. I remember it took place in a toy shop. I think a family of puppet mice lived in the store? I remember most of all that at the end of the intro, the door of the shop would open and a red tricycle would roll in, unaccompanied. I remember being about five and being a little creeped out by that. I asked my brother if he knows what I'm talking about, and he says it's Today's Special, but I could swear that's not it since that show aired on Nickelodeon and took place in a department store. Does anyone know what show I'm talking about?
EDIT: Sorry. The program on Nickelodeon wasn't Special Delivery, it was Today's Special.
