Where's Wally? (1991) : 1x5

There is trouble in the Land of the Deep Sea Divers – the sea is draining. Wally is sent by the Wizard Whitebeard to help solve the problem. Wally meets Lucinda, the mermaid who was in charge of guarding the great sea plug. Unfortunately for Lucinda, a ship full of plug-snatching pirates came and took the plug when she wasn’t looking. Now Wally, Woof and Lucinda have to try to get the plug back and the sea level restored. Meanwhile, Odlaw teams up with Pegbeard (the pirate captin who stole the plug), and the evil pirate octopus Sidney. The pirates are draining the sea to uncover the treasures that have sunken to the bottom, while Odlaw is after (as always) Wally’s magic stick. Wally (and Woof) travel to the bottom of the sea, nearly avoid being eating by a shark, fight off pirates, meet mermaids (and mermen), and take a wild boat ride. Will Wally be able to plug the sea and restore water to the land before it’s too late? Yes.
