Three children visit their friend Bethie's clubhouse where they are encouraged to be as silly as possible as long as they learn and do well in school. Everything is silly at Bethie's clubhouse, the door tells knock-knock jokes, the books jockey to be read first, and the TV reminds Bethie when her favorite show "Ivana the Iguanna's Beauty Tips" is on. Add to that an assortment of silly visitors like Kitty Kat Man, Captain Schnorer the Worldwide Explorer and various talking animals who all break into wonderful musical numbers while educating the kids.
