- "Every year, us big kids, choose a kid to run in the Big Race"
- ―T.J. about the Derby
The Kindergarten Derby happens every time of the year where older kids pick kindergarteners to race against each other. The race has 3 main parts:
- Water pool
- Clown Slalom
- Valley of distraction
Mikey mentions, in Kindergarten Derby, that he was unable to complete the Derby and showed hatred for it ever since until Tubby used his wish to force King Bob to end the Kindergarten Derby once and for all. Tubby with Mikey are the only known winners of this competitions.
- The 25th Annual Kindergarten Derby was presumably the last one.
