Metal

Metal, unlike glass, is indestructible and is very dangerous. It can only be avoided by destroying the glass connected to it. Hitting it with the Explosive Ball Power Up will destroy the glass conected to it, but not the metal piece itself.

Metal is not completely unaffected by the balls - It can be pushed in Low Gravity if its glass is not being held to stone, or by any string s, or if you use the Explosive Ball to destroy the connecting glass. can be useful for saving balls or saving yourself from being hit.

It also acts as a support for most obstacles. Look closely to where a glass pane or bar is anchored. There you will find metal. Moving Columns are also made of metal. In the Bowling Easter Egg, the bowling pins are on a metal platform.
