It's the first day of spring, and Cowboy Curtis comes over and gives Pee-wee some seeds to plant, saying that all kinds of trees and plants grow from them. Thanks to Clocky, the seeds grow right away. They have grapefruit for snacktime and Randy squirts juice at Pee-wee and Cowboy Curtis, so they both squirt juice back at Randy. The King of Cartoons brings over his family, consisting of the Queen and Prince, and Magic Screen shows everyone a film about sexual reproduction. Pee-wee tries out for little league and doesn't make the team, so Ricardo tells him that he should find a sport he is good at and do that instead.
