See the updated rules for the event.

I believe the Bloons on the Blue Tiles must be popped before you can pass a blue gate along that path. The lightning tiles give you more energy if you rest on them. The arrow one only permits you to move left or right, once you decide, you aren't allowed to return to or move over that space again.
