Ninji (toy)

Ninjis are Ninji toys in Mario vs. Donkey Kong. They have a windup key on their back like all the rest of the mini-minions. They jump up and down in one spot, acting much like the second type of Ninjis in Super Mario Bros. 2, and can give Mario a boost at getting to higher places. They have few appearances in the game, first seen in Fire Mountain.
