Harvest Feast.Mr. Beanly is sent out with another batch of invitations, this time for King Nogburt's Harvest Feast. Everyone is invited, but Beanly loses Wooly's invitation. Coincidentally, Wooly decides to invite all his friends to a feast of his own, but no one is home to receive his invitations. Back at the castle, Gimmick notes that Grundo has received above average rainfall this year -- yet King Nogburt's kingdom is suffering a drought. Tweeg rolls into town, and begins peddling a rainmaking machine as his latest scheme. Gimmick shows off the Subwater Boat to the King, and the two of them go for a dive, and get lost in a series of tunnels leading away from the castle moat. After the two of them have been gone too long, Teddy puts on his scuba suit and goes after them. Gimmick and the King stumble across a chamber with ancient controls for operating an aqueduct system, which amazingly enough has a Crystal slot in it! The Gutangs appear, and work to tighten down a series of valves to cut down the water supply still further, in order to weaken the kingdom in preparation for an invasion. Gimmick and the King are captured, but are frightened away when Teddy appears wearing his scuba gear. Gimmick uses the Fourth Crystal to activate the aqueduct mechanism and restore the water supply to normal, and the three of them return to the castle. The King's subjects lose interest in Tweeg's device when the water flow returns to normal. King Nogburt realizes that Wooly hasn't been invited, and the Trio, Eunice, and Aruzia take the Airship and bring back Wooly and his food, making for a bountiful banquet, which everyone is thankful for.
