A new cast of characters greeted the kiddies in 1975 with the addition of Hanna-Barbera Land. Among them were Yogi Bear, Scooby Doo, Fred Flintstone, the Banana Splits among others. This was a very nice children's area with an assortment of kiddie rides and it's very own junior sized wooden roller coaster. The area became Nickelodeon Central in 2004 and changed to Planet Snoopy in 2010.
When the park opened in 1973, there was a little known playgound on an island near the covered bridge. It had an attraction known simply as the spinning barrel house along with a spiral slide with a windmill on the top. This small playground was removed around 1975 with the addition of Hanna-Barbera Land.
