Take them to the Neggery.
You can trade them in the neggery or, let your neopet(s) eat them.
Neggs are the Neopian equivalent to eggs, but they grow on trees. They are given out in random events on Easter, but you can get them other times too. Your pet can eat neggs, or you can give your neggs to the Negg Faerie at The Neggery in the Terror Mountain Ice Caves. Neggs at The Neggery can be saved up using a system of Negg Points, and using Negg Points you can buy even rarer Neggs, some that, when fed to your pet, change it.
You go to the neggery in terrow mountain
If you get a negg, you take it to the neggery and get neggpoints to get cooler neggs.
Some neggs are magical and gives powers. Some neggs are just regular neggs, edible for your Neopets. Some of these can be traded in for a certain amount of points at the Neggery, which can be redeemed for magical Neggs.
