Lightpopper

The lightpopper is a monkey tower that shoots waves of light, damaging or popping the bloons, depending on the wavelength. He looks like a normal monkey through every upgrade, and can shoot light through his hands. Unupgraded, he shoots red light. The shot looks like a real wavelength of light, so it allows you to see the length of them. The lightpopper also shoots rather speedy. The shorter the wavelengths, the stronger it is.

Path 1

 * Green Light - Decreases wavelength to green light. Longer range also included.
 * Blue Light - Decreases wavelength to blue light.
 * Ultraviolet - Decreases wavelength to ultraviolet light, burning bloons instantly. Longer range also included.
 * X-rays - Shoots x-rays, disentegrating every single bloon in its path.
 * Gamma Ray Tsunami - Covers most of the track with gamma rays, absolutely destroying all bloons at millions of degrees. Unlocked at rank 40.

Path 2

 * Longer Range - Self explanitory.
 * Long Lasting Light - Self explanitory & more powerful light.
 * Ultraviolet - Decreases wavelength to ultraviolet light, burning bloons instantly. Also used in path 1.
 * Laser Vision - Now shoots lasers from eyes and left hand.
 * Cosmic rays - Disentegrates the bloons at million to billions of degrees. Unlocked at rank 45.
