Nibble Bloon

The  is a very weak bloon, encountered only in technological areas, usually replacing Red or Blue Bloons. It moves at the speed of a red bloon and has 4 HP. It gives $7 when popped, however. It has some abilities:
 * Write: Deals 8 HP damage to the nearest tower.
 * Unsign: Will randomly happen when spawned (25%). Gives $15 instead of $7 but has twice the health and moves 33% faster. It can't deal damage, however.
 * Undo: Heals 3 HP.
