t's Gumba's birthday! Gumby buys his mom a plant and swings by Professor Kapp's place to give it a ride in his centrifuge to make it grow better. He decides to ride too, just for fun. Unfortunately, the bumbling professor gives him 10 G's instead of 3, and he's horribly flattened. Gumby shrugs off the episode and gives the plant to his mother, who plants it in the front yard. The next day, foliage covers Gumby's entire house, trapping the family inside. Gumby's folks instantly assume it's their son's fault and force him and Professor Kapp to cut it all off.
