Garbage block

Garbage blocks are obstacles appearing in Tetris Attack. Depending on the side of the player, it is either colored red or blue. The size of the block depends on how many panels a player clears in a set amount of time. More cleared panels results in a bigger garbage block. To clear them, the player must clear panels that are touching it. This causes the bottom-most row of the garbage block to turn into regular panels. If additional garbage blocks are directly touching the affected garbage block, the bottom-most row of those blocks are affected as well.
