Name: Dekuhats
Location: Kokori forest, Deku swamp, anywhere with plants that has gaps to be crossed.
Description: like the Peahats in twilight princess, Dekuhats are mobile hookshot targets. They are indestructible and use leave as helicopter blades to hover. They will either stay in one place, or have a predetermined route, like those floating bombs in Minish cap.
Hitting one with the hookshot pulls Link to them and he automatically hangs from the bottom, pressing the action button with cause him to drop to whatever is below him. While hanging, he will move with the Dekuhat, and can use the hookshot again to hit another target and be pulled away.
Came up with this mainly so Link can get from treetop to treetop without us needing to place hookshot posts sticking out of the canopy, this seems more elegant a solution.
