Giga Bell

The Giga Bell is a power-up exclusive to the Bowser's Fury mode of Super Mario 3D World + Bowser's Fury. It transforms Mario into Giga Cat Mario, although its power can only be accessed by collecting Cat Shines, with the required number increasing as the story progresses.

By default, the Giga Bell resembles the standard Super Bell, but is much larger and has cat ears, whiskers, green eyes, a more orangish coloration, and a much deeper ring, complete with a low-pitched meowing sound. It also rests on a golden, Sphinx-like pedestal with a short staircase leading up to the top, sometimes with a few stacks of coins resting beneath. When it has been corrupted by Fury Bowser, however, the bell becomes black and spiky, with a dark purple aura surrounding it, and it appears to be asleep. If the player has enough Cat Shines in their possession but Fury Bowser is inactive, then the bell will remain asleep, but take on a tan, stone-like appearance.

A total of three Giga Bells exist throughout Lake Lapcat, each one surrounded by its own small group of islands.

Trivia

 * The Giga Bell is one of only two power-ups in the series that is shown to be capable of speech, the other being F.L.U.D.D.
