Moon Boss

The Moon Boss is the 4th boss in Red Ball 4. He appears as a large box about the same size as the Monocle Boss, but styled similarly to the Electric Box, being blue with an outline. He also has glasses with red rims that turn yellow when he's dizzy or hurt. Unlike most bosses, his teeth are flat rather than pointed.

Behavior
Phase 1: The boss will charge across the screen, then enter his stunned phase and flip gravity. After being hit 3 times, he will change the gravity to upside down if it isn't already, and leave the screen.

Phase 2: Two lasers will come in from either side of the screen, and leave a narrow gap, then move side to side in unison. Red Ball must move back and forth to avoid being hit by these.

Phase 3: The boss comes back, and starts charging back and forth while flipping gravity, changing it every time he hits the ceiling or floor.

Trivia

 * He shares music with Monocle Boss and Samurai Boss.
 * He is the only boss to take place on a different planet.
 * His animations for hurt and stunned are the same.
