A Morph Jump eliminates the need to "mantle", or grab onto a ledge when trying to jump up at something that requires the Morph Ball to traverse. Jump at the ledge you're trying to reach and tap ZL while airborne to instantly morph and you should be able to land on the thing you're aiming for. This technique can be used in conjunction with Flash Stalling. You can also use this along with Spider Magnet grappling or wall jumping as well.
