Grapple points

Grapple points can be found everywhere in the world, most commonly in caves and on Bosses and you can fire a Hookshot at them to grapple to them

Appearance
They look quite a bit like archery targets but attached to walls and ceilings

Trivia

 * When aiming the Hookshot in the general vicinity of the Grapple Point it will give you VERY strong aim assist for the Hookshot
