When Tom, Twigs and Bertie pull a boat out of the slime lake they decide to play pirates. Tom draws a treasure map and then he goes off with Twigs to make a pirate flag. Meanwhile the Mushas climb aboard, pretend to be Bertie's friend and then convince him to set sail to find the treasure.

They arrive at the island, which is actually a giant fungo-disc, and when the Mushas plant a flag in it and call it Musha Island, it starts spinning wildly out of control and heads for the clubhouse! Show less
