After you have performed the action, remove the corresponding Action card from its slot. Move the Action cards left of the new gap rightward to close the gap. Finally, place the used Action card in the empty leftmost slot.

If you use the leftmost Action card, you do not move any cards.

EXAMPLE: After you have performed the Projects action with strength 3, place the Projects Action card all the way on the left and move the Action cards in between 1 slot to the right.

This increases the strength of the Rock animals and Forest Animals actions by 1, i. e., to 2 and 3, respectively.

The Projects action only has a strength of 1 on your next turn. The Water Animals action does not move, and keeps its strength of 4.
