Nectar egg

A nectar egg (known as an egg prior to Pikmin 3) is a white, semi-round object found in alcoves of caves, and on specific places aboveground. It is unknown if they come from any kind of creature or plant and it may be possible that they are merely egg-shaped containers. They can be attacked, and when broken, they release nectar, although they can also release other things. The eggs held by Honeywisps in Pikmin 2 function identically to grounded eggs. In Pikmin 4, large versions of nectar eggs can be found. These 'large nectar eggs' release multiple drops of nectar when broken.

To destroy an egg, it must be attacked with Pikmin, punched at a few times with a leader, or destroyed by an enemy projectile, like a Gatling Groink's fireworks.

For Pikmin 2, it is advisable to throw a Purple Pikmin onto an egg, as this will immediately break it and contained Mitites will be instantly defeated. It is also recommended to destroy an egg with a leader, as a Pikmin thrown at the egg may drink the nectar after being called back, wasting it.

Contents
In Pikmin 2, the contents of an egg are picked at random from a list, and they're only chosen on the exact moment the egg breaks, not when the egg is created (i.e. they're not chosen when the area or cave loads). Not every outcome has the same probability of happening. In story mode, if the game decided on a drop of spray nectar, but the player has not yet unlocked that spray, the outcome will instead be changed to a single drop of nectar. The chances (assuming both sprays are unlocked or it's outside of story mode) are detailed in the following table:

In Pikmin 3, certain eggs are programmed to always drop certain objects. For example, some of the eggs in the hollowed-out tree in the Tropical Wilds where the Juicy Gaggle is found are pre-programmed to always drop bomb rocks – the only known ones to do so. Other than that, some eggs in Mission Mode always drop ultra-spicy spray. Most eggs in Story mode can drop either nectar or ultra-spicy spray. If ultra-spicy spray has not been discovered, they will only drop nectar, as ultra-bitter spray and Mitites are not present in this game.

In, eggs can drop nectar, ultra-spicy spray, or raw material. Occasionally, the Sunsquish and the Downy Snagret can be found inside eggs.

Locations
There are no nectar eggs in the first game, but they can be found in many places in Pikmin 2 and Pikmin 3. Their location in areas is always constant, and they always respawn whenever the area is entered. Underground, there are several sublevels with eggs, some having more than one. Eggs that fall off the ceiling of caves will instantly break when they reach the ground.
