Kinetic Orb Cannon

From Wikitroid, the Metroid wiki

A Kinetic Orb Cannon is a cannon that can launch spherical shaped objects, like the Morph Ball long distances. They are found on Aether and on Elysia in SkyTown. In the latter location, some Kinetic Orb Cannons need to have power restored to them by entering them and using the Boost Ball to quickly go in circles, causing it to turn. Something very similar appears in Metroid Zero Mission. It sends the morph ball upwards at speeds that can break any blocks. It can even send you up through pit fall blocks.
