There are a number of boosts that you can buy with shells to assist you in your Hatchlings gameplay. You can find these in the Boosts section of the Hatchlings Marketplace.
To purchase a boost, simply click on the item you wish to buy, then confirm the purchase in the popup window.
Diamond Key
Diamond Keys can be used to unlock Exclusive series. Read about Diamond Keys and Exclusive series here.
Challenge Keys
Challenge Keys open challenges, and add a new dimension of fun to Hatchlings gameplay. Read all about challenges and Challenge Keys here.
In addition to individual Challenge Keys or bundles of Challenge Keys, you can also buy a Challenge Key subscription in the Boosts section. A Challenge Key subscription is the best value we offer on Challenge Keys. It allows you to claim 2 keys per day for either 7 or 31 days.
Be sure to log in each day and claim your subscription keys! To do so, click the Challenges icon and then click the Subscription badge at the bottom right of the window, near your Challenge Keys. Any unclaimed keys from your subscription will be lost.
Turtle Key
You can purchase and use a Turtle Key at any time to open a locked collection of any color (excluding Exclusive collections). Learn about opening new collections here.
