Cleansing Foam

Cleansing Foam is the third upgrade on the first path for the Monkey Engineer. It allows the Monkey Engineer to shoot a special foam that can remove Regen, Camo, and Lead properties of bloons. Only 3 blobs of foam can be on the track at once (unless the Monkey Engineer is placed on the socket of power in The Crubicle Special Mission). If a certain amount of bloons go over the foam, it dissapears, regardless of if they are camo, regen, or lead.

Trivia

 * The Monkey Engineer doesn't aim with his gun, so the globs of foam can come from the Monkey Engineer's back.
