Very, very slow, and cant move while its organs are being played. If no smaller crasher of any type is piloting it, then it wont move at all. The playing skill of said pilot crasher is relative to its speed.

Each pipe played provides a different effect to ally crashers, and pipes played in combination boost that effect by an amount equal to pipe count * 10 as a percent. Crashers will try to mash organ keys to play, by a speed of 1 key every 8 - speed of said crasher seconds, and each boosts lasts as long as the note is played + crasher speed * 10 as a percent.
Pipe one boosts ram power by 3, pipe two boosts power by 1, pipe three boosts vision by 20%, pipe four boosts speed by 2, and pipe five boosts health by 4.
