Fury Block

Fury Blocks are a type of block that appear exclusively in the Bowser's Fury campaign of Super Mario 3D World + Bowser's Fury. It is a slightly larger, metallic variation of the Brick Block with Bowser's emblem plastered on all sides of it in black. As the name may suggest, these blocks cannot be broken by normal means, and can only be broken using the power of Fury Bowser's fire attacks. When a fire attack hits the blocks, they will break, revealing whatever was behind them. While Fury Bowser is active, the Bowser emblem on all Fury Blocks flashes red.

Every major island in Bowser's Fury contains a mission called "Blast the Fury Blocks," which requires Fury Bowser's presence in order to break a set of Fury Blocks and gain a Cat Shine that was hidden by them.
