The first helmet Ozzie tries on was on display in Artie's office during Season 1. The second helmet he tries on was the one worn by Pete when he was playing with a sword in a previous episode.

Pete mentions Mr. Toad's Wild Chariot Ride after the runaway wagon disappears. Mr. Toad's Wild Ride is a theme park attraction and dark ride at Disneyland Park in Anaheim, California.
