From the Super Mario Wiki
Lucky Cat Mario is a form of Mario introduced in Super Mario 3D World. In this form, Mario has identical abilities to Cat Mario, and when he uses a Ground Pound, he can also turn into the invincible Golden Statue Mario – akin to Tanooki Mario's Statue Mario form, except he earns Coins and defeats enemies on contact. Mario looks exactly like Cat Mario in this form, except he wears a red bell collar.
The Lucky Bell, the power-up required for this form, begins appearing in World Mushroom, in the level World Mushroom-2: Spiky Mount Beanpole. If Lucky Cat Mario collects a Super Bell while in this form, he "downgrades" to Cat Mario, unlike collecting a Super Mushroom while Mario already has a power-up. Lucky Cat Mario strongly resembles Manekineko, an entity from Japanese culture.
Lucky Cats Toad, Mario, Princess Peach, and Luigi.
