Bomb rock

Bomb rocks, also written as bomb-rocks, are explosive rocks with cracks through which glowing yellow and red energy flows. Upon being activated, such as by being hit or set down, a bomb rock will light up and emit a hiss until it eventually violently detonates, damaging Pikmin, leaders, enemies, and some obstacles. The explosions can trigger a chain reaction if they hit other bomb rocks. Some enemies utilize bomb rocks to their advantage, and some enemies also have notable interactions with bomb rocks, such as being able to eat them.

In, bomb rocks are slightly smaller than a Pikmin can be carried by Yellow Pikmin. A bomb rock explosion will instantly make all bomb rocks in the vicinity explode.

In, bomb rocks are remarkably large, serving as obstacles more than tools, and can not be carried by Pikmin, only pushed around slowly by leaders and enemies. A bomb rock that gets hit by an explosion will only initiate its countdown. Throwing a Purple Pikmin directly on top of a bomb rock will make it explode instantly.

In, bomb rocks are in between the sizes they were in the prequels and can be carried by any type of Pikmin. An explosion triggers a neighboring bomb rock's explosion in around half a second, resulting in quite a fast chain of explosions. Also, a bomb rock's explosion will instantly unearth a buried object in its range.

In Pikmin 2... Again?
Mad bombs are obstacles in Pikmin 2... Again?. Based on the bomb rocks in, they are larger bomb rocks with glowing red interiors. They are too large for Pikmin to wield effectively, and so can not be carried by them.

In Pikmin Adventure (DrTapeworm version)
Bomb rocks appear in Pikmin Adventure, in both the small and large sizes. Small bomb rocks are found in piles of three, contribute to the bomb rock counter when collected, and can be thrown at enemies. The large ones appear as hazards and are the same as they are in.

In Pikmin Search
In Pikmin Search, bomb rocks can be carried by Brown Pikmin. Otherwise, their use is practically identical to their incarnation.
