New Super Mario Bros. U - Mini Mario

Mini Mario is a form Mario takes after obtaining a Mini Mushroom. This allows players to jump higher, walk on water, jump on enemies without killing them and fit through mini Warp Pipes. However, if you get hit in this form, you lose a life rather than reverting to regular-sized Mario. It mostly behaves in same way as it did in New Super Mario Bros. Wii, the only difference is you can also run up and down certain walls.
