Super Bell

The Super Bell is an item introduced in the game for the Wii U, Super Mario 3D World. It is a golden striped bell with beady eyes. When obtained, Mario, Luigi, Princess Peach, Toad, Bowser, or Rosalina will transform into their cat form, which allows them to run up walls, slide into enemies, attack in midair, and climb up Goal Poles. There is also another power up called the Lucky Bell which turns Mario again into a cat, but when he ground pounds under a certain condition, bonus coins will appear. With a Lucky Bell, the player can also turn into a statue by ground pounding but if enemies touch them, they'll get defeated.

In Mario Kart 8, the Super Bell is referenced as a racing cup called the Bell Cup and as a track called Super Bell Subway as a part of the Animal Crossing × Mario Kart 8 downloadable content pack for 2015.
