Brolder

Brolders are enemies resembling boulders that make their first appearance in Super Mario 3D World.

Super Mario 3D World / Super Mario 3D World + Bowser's Fury
Brolders generally appear in lava-filled levels where they hide underground until they are approached, at which point they will emerge from the ground. Brolders' only method of attack is rolling in the character's direction to harm them. However, when they are hit by an attack, they temporarily become common boulders with no eyes or arms. In this state, they can be picked up and carried by the player, then tossed in a preferred spot. Brolders can be defeated by being tossed into the lava or by having another Brolder tossed at them.

If a Brolder is not attacked periodically while in its boulder state, it will start to rumble and eventually turn back to normal, beginning to roll towards the player again. If a player is holding a Brolder when this happens, they will take damage before dropping them.

Their leader, Boss Brolder also makes an appearance as the boss of World 4 before reappearing in Brolder Blockade Is Back and Boss Blitz

Mario Golf: Super Rush
Brolders appear on the Ridgerock Lake course in Mario Golf: Super Rush. They roll across the course, tripping players if they make contact with them. They can be destroyed by super-dashing into them.
