In Pikspore
Skitter Bombs are skitterlings in Pikspore that disguise themselves as bomb rocks. This is a clever ruse, but with a certain upgrade, leaders can pick them up and throw them. Other than that, they're the same as standard Skitter Leaves, only with more vitality.

In Pikmin: Decayed Leaf
The Skitter Bomb is a new enemy found in Pikmin: Decayed Leaf. The creature, at first, resembles a mere bomb rock. If approached, it will reveal itself as a bomb rock with two red eyes and four, flat, black legs. The creature will run around quickly. However, if it touches any entity, it will instantly start its fuse; before eventually exploding. This can be extremely dangerous if one runs into your squad. However, this can be used to your advantage if one is found by a larger enemy, or a group of smaller enemies. You can also punch a Skitter Bomb to set off their fuse.
