Squack egg

A Squack Egg is an egg the size of an average Squack. It has a living Squack inside It is triggered usually between when half to two thirds of the egg's health is gone. Any Squack can come out of a Squack Egg. However, the chances aren't equal. Assuming all of the hazards that Squacks have are in a den, Fiery and Watery Squacks have a 33% chance each of their appearance, a Toxic Squack has a 20% chance of being in the egg, a Goopy Squack has a 10% chance of being in the egg, Aggressive Squacks have a 3% chance of being in an egg and Acidic Squacks have a 1% chance of being in a randomized egg. However, some Squack Eggs will have a chosen Squack already. For example, the second floor of the Squack Cavern has an Aggressive Squack in an egg already and it will always be there. Squack eggs can also be like a reward as they will have a chance of a Nectar Goolix with a massive amount of nectar or they will hatch Squacks that have almost no ability to kill Pikmin and could be used as a way to raise Pikmin numbers.

Strategy
Have a massive amount of Pikmin mob the egg, as it has the same health as a bulborb. Call nearly all of your Pikmin back when you have nearly reached half of the health depleted. Then have between 5 and 10 Pikmin continue to beat the Squack Egg and eventually the Squack will come out. It is good to have a small amount of Pikmin attack the Squack egg because when the Squack hatches the Pikmin will chase it and the Squack may lead the Pikmin to an enemy. Than defeat the Squack as you normally would. If you're lucky, there may be nectar inside the egg for Pikmin to drink.
