Energy Race is a special event that offers extra rewards for exploring temporary islands. When it is active, an icon with a blue gift box appears in the bottom left corner. 

 Be careful, the same icon is also used for other events like  Opal Hunt or  Rune Hunt.

How to get racing flags?

Racing flags can only be collected for using energy on temporary adventures and in the Temporal Anomaly.

To get the flags, cut down different objects like grass, trees, and rocks.
