Tetris blocks

Tetris blocks are the main characters in the Nitrometris areas of mega Mash. They are Tetraminos made up of four Cuboy heads of the same colour that take on different shapes. A shape can be rotated by moving the ← and → arrow keys in Mega Mash. Pushing the ↓ arrow key in Mega Mash causes them to move faster down. In Rubble Trouble Moscow, the blocks move when the player moves the mouse, always being above the mouth. There is no way to make them move faster in Rubble Trouble Moscow, which was a complaint by some fans. Below are the shapes made by the coloured heads in Rubble Trouble Moscow as well as in Mega Mash.
 * Orange/Purple Heads - L
 * Yellow Heads - Block
 * Red/Light Green Heads - Z
 * Light Blue Heads - Stick
 * Pink Heads - T

If a row of Cuboy Heads are made, regardless of colour, they will disappear and the player will be rewarded points. I Rubble Trouble Moscow, a Drill is fired on the same level as the made blocks. If it so happens Nitromtris are stacked up high enough that a Nitrometres comes down and there isn't enough space for it to fit on the screen, the player will lose one of the Hearts in Mega Mash, losing an ammunition for the Minigame tool in ubble Trouble Moscow. This is the only way to die in Nitrometres. In Mega Mash, if a block is on a Zone Switch, and there are Nitrometres, stacked up, and the player removes the block from the Switch, the Nitromtres stacked up will become platforms for the player to move on, when not in the Nitrometres zone. The player has to sometimes do this to advance farther in the levels in Mega Mash.
