Following his previous adventure involving Alice from Wonderland, Uncle Wiggily sets out again and stumbles upon the Mad Hatter's tea party, joining Alice, the March Hare, and the Dormouse. The party is perpetually stuck at tea-time with no food due to the Hatter's broken watch, leading to nonsensical interactions. When a threatening "Wabberjocky" cat arrives intending to capture Uncle Wiggily, the chaotic March Hare unexpectedly saves him by smashing the Hatter's watch with the rabbit's crutch; the uncoiling spring catches Uncle Wiggily's leg and flings him safely back home, leaving him to ponder the strange adventure.
