Burst Bomb

The Burst Bomb is a sub weapon in Splatoon and Splatoon 2.

Splatoon
Burst Bombs are spherical balloons filled with ink that explode on contact with any surface, like a wall or floor. They use less ink than Splat Bombs, and Suction Bombs, and therefore cause less damage.

Burst Bombs are one of three usable Sub Weapons in Octo Valley, unlocked with Power Eggs and selected via once available. They cannot be used in amiibo challenges, making Splat Bombs the only usable Sub Weapon for the Hero Roller and Hero Charger. They can also be used during the Credits.
