Bomb egg

The bomb egg is an obstacle that appears in the game Pikmin: Invasion of the Giants, In the Forgotten Sandland It will look like a black egg, and you will probably think that they is some new type of eggs. In actuality, it is a cleverly disguised bomb rock!(the bigger size, not the type that can be picked up by yellow pikmin, and/or orange pikmin.) If you have your pikmin swarm it, or make throw them to break it, it will put the life meter above it. The life meter will only go down when hit, so one might think that it is really losing life as it is hit.

How to defeat
Simply grab one purple pikmin, throw it next to the bomb egg, and the weight of the purple pikmin will take away some of the life. Repeat this tactic, and when it has one bit of life left, then go punch it with your captain. If you have the Boom Guard, you will not be harmed. If you do not, then only a small bit of life will be taken, and you will be knocked back.
