With the help of Hedgerow Huppy, the inventor, Bugs grows a Christmas tree-sized carrot. He runs out of decorations and finds that Huppy has a not-quite-perfected invention that makes sticky, long-lasting bubbles. Huppy mistakenly gives Bugs a tank of helium instead of compressed air and the helium-filled balloons on the carrot tree take it airborne. Elmer and Bugs have to track it down with a helicopter.; Porky invents a jet-propelled pogo stick.; Daffy wants Yosemite Sam to enter him in the unusual pet contest.; Tweety finds a box full of mechanical toys that look just like him and uses them to trick Sylvester.
