An egg is a white, orbular object found in alcoves of caves, and on specific places on land. These are the eggs of some insect - an unknown one, however. They usually contain nectar, but may also contain sprays or Mitites. It seems that the eggs seen being held by Honeywisps may actually be connected to these ones, due to their appearance. To destroy an egg, simply attack it with your Pikmin or punch it a few times with your Captain. Eggs pose absolutely no harm to either one. It is advisable to throw a Purple Pikmin onto an egg, as this will immediately break it and contained Mitites will be instantly defeated.
There are no eggs in the first game, but they can be found in many places in Pikmin 2; each number represents the number of eggs in a group. Also, note that eggs may appear in almost all underground locations.
