The Birthday Present:
It's Gumby's birthday, and he's getting a beautiful grand piano. Prickle and Pokey tow it home on the trailer. While they stop to pick out a matching candelabrum, the Blockheads detach the trailer. Prickle and Pokey don't notice until they get back to the barn, and, of course, by the time they get back, the Blockheads have hidden the piano somewhere. As J runs out as a decoy, G starts building a wall of blocks to hide it. Prickle and Pokey find a freshly-painted sign reading "This Way to Piano", but they choose to follow the trail of paint instead, which leads to the piano, but no Blockheads. When Gumby receives the piano and tries playing it, it sounds a little funny. The Blockheads were hiding inside.
Just Train Crazy:
While Gumby's out for his dental appointment, Denali accidentally smashes his prized model train. In true wacky sitcom tradition, Prickle and Pokey have to replace it before he gets back. While perusing the trains in Toyland, they're given a hard sell by a sentient engine who offers them a free ride. They shrink themselves down and hop in, rather pleased to find that the train can take them instantly to wherever they want to go. However, the train never stops, so they have to pass it up. Fortunately enough, a train just like the one they're looking for shows up when they get back to Toyland, so the cartoon can end now.
Wickiups and Bulrushes:
In honor of Native American Week, Gumby's band is putting on concerts for a different tribe every day, starting with the Chippewas. When Goo and Denali show up at the reservation to hammer out all the details, Goo meets a little girl who wants to ride on Denali, but first she needs to gather some bulrushes, so Goo helps. While they're out, they notice a distinctly unnamed rival tribe preparing to attack. Goo flies them back to the village, where they prepare to repel their attackers. Thanks largely to Goo and Denali, the anonymous evil tribe is beaten back, and the day is saved.
