Wall-nut Bowling was a K'NEX set based on the Wall-nut Bowlingmini-game from Plants vs. Zombies. It is a stereotypical bowling game, with a Wall-nut as the bowling ball and a Zombie and five small structures as the pins. The set includes 65 pieces that, when assembled, create the ramp the Wall-nut rolls down and the five small structures that act like pins.
To play, a person must place the Wall-nut on top of a buildable ramp made of K'NEX pieces and set the Zombie and the small structures to the correct positions. Then, the Wall-nut must be pushed down the ramp so that it will knock down some, or all, of the pins and the Zombie.
