Waldo and Wenda head to Tahiti to help Wizard Wavybeard find his lost Wave Key. Odlulu sees the Wave Key as her chance to win the surf competition and earn a statue of herself on the beach. The Wanderers and Odlulu have a surf-off, and the winner gets the key.

When Whitebeard attempts to magically enhance his voice for a singing duet with an old Wizard friend, he accidentally switches bodies with Arf. It's up to Waldo and Wenda to reverse the mix-up before the concert!
