Before you explore the Boonieverse, make sure that your Boonies have enough energy to challenge other Boonies. Click the “Team” tab in the left bottom corner to check their energy level. If some bars are not entirely green, click on “Heal” to make sure that your Team is prepared to challenge other Boonies.
If all your Boonies lost their energy you may be unable to play for a while. They need to rest first. Once your Boonies have rested a while, you will be able to heal them again and continue playing.
If you don’t care to wait you can use some Crystals to heal them immediately after or during the challenge:
We hope you will have lots of fun challenging other Boonies.
