Break Blocks are a kind of item in Mega Jump. Their appearance differs in each stage, but all have the same properties. They are usually a square block with a design in the middle.
When a break block is stepped on, it will give the character a short boost upwards, however, the design or shape inside the block will disappear. If stepped on again, the block will break and will also disappear, giving the player 2 jumps before the block shatters. Break Blocks sometimes have things hidden inside them, which can be Coins, Powerups, Boost Stars, or even Fireballs and Super Novas.(the latter two appear less often) Like most obstacles, these will be destroyed in one hit from the Balloon, Fireball or Super Nova
