It's little sister Minga's birthday, and that means a full day at Pumpkin Land Amusement Park, the pumpkinest place on Earth. There's a plethora of pumpkin-based foods, such as Pokey's much-desired Pumpkin Puff; pumpkin-themed rides like the Pumpkin Train and the Pumpkin Ferris Wheel; and, of course, attendants with evil Jack O'Lantern heads. Hooray! The action revolves around the Blockheads, who've jumped the fence and broken into the park. After a merry chase, the Blockheads are flattened by a giant pumpkin, and Pokey eats so many Pumpkin Puffs that he turns into a pumpkin himself.
