Mario vs. Donkey Kong 2: March of the Minis
The success of the Mario Toy Company's earlier toys, the Mini Marios, was so great that it allowed them to expand to sell other mini toys, including Mini Peach, and Mini Donkey Kong toys as well.

Mini Toads are playable characters in this game as well, but Special Kit 1 (which is unlocked by completing 3 minigames) has to be unlocked first in order to use them. If a Mini Toad comes in contact with a Fire Flower, it will become a Fire Mini Toad.
