# Seasonal Eggs
## Where can I get the Eggs?
The seasonal eggs are on sale exclusively during the seasons. The merchant will offer a limited number of seasonal eggs each season for the price of 500 [$GRVE](https://croskulls-organization.gitbook.io/croskull/erc20-tokens/grave-usdgrve) each. (*The price may vary depending on the season*)\
\
Seasonal eggs are usually limited to 2,200, but depending on market conditions and the season their supply may vary. These special eggs will hatch into seasonal pets by using the [laboratory](https://croskulls-organization.gitbook.io/croskull/ecosystem/laboratory) feature.

## What are eggs used for?
The seasonal eggs are very rare items and are used to generate a seasonal pet. With pets you can participate in [Missions](https://croskulls-organization.gitbook.io/croskull/ecosystem/missions), special event challenges that will allow you to get rewards and, in the future, play the “CroSkull Rivals” game.

The CroSkull will continually strive to provide more Gamefi and more usefulness to the function of pets, during the adventures to expand the Metaverse of CroSkulls.

## What can I do with the eggs?
Eggs are NFTs, you can hatch them in our [laboratory](https://app.croskull.com/#/laboratory), or sell/trade them in the NFT marketplaces ([Ebisu's](https://app.ebisusbay.com/) or [Minted](https://minted.network/)).\
The hatching of the Pets' eggs takes place in the [Laboratory ](https://app.croskull.com/#/laboratory)section of our [Dapp](https://app.croskull.com/#/#/laboratory).\
The hatching works as follows:
* First you need to approve the hatching contract
* After that you can start hatching the eggs.
You will be able to hatch up to a maximum of 15 eggs in a single transaction. This will allow you to save on some gas fees. After hatching, your egg will have hatched into one of the seasonal pets!
