If the pirates left Ventureland to head home, Mickey can recieve the Solve Jim's Riddle quest by talking to Jim the Puzzled in Ventureland. This quest is the first of the three riddles that he asks Mickey to solve.
To solve the riddle, Mickey must feed paint into the Tiki Mask's mouth on top of the Tiki Hut. This will cause a TV Sketch will fall from its mouth. Returning and talking to Jim will complete the quest, and Mickey will be rewarded with 50 E-Tickets.
