A pair of objects that have no collision but can be grappled to with the Grappleshot. Once the player reaches the hook they get flung forward at most 2 tiles.
the hanging variant can only be grappled in midair, and the regular one only on the ground.
the hook can maybe also be attached to other objects and surfaces for player to pull them. i.e. pulling moving platforms to you, pulling crates or pillars, etc.
(inspired by a similar mechanic in Pipistrello and the Cursed Yoyo)
