Beepboxers are a sub-species of Boomboxers from Super Paper Mario. Their heads are shaped like radios or boomboxes. Beepboxers first appear on Planet Blobule, which may show that they are actually alien species hailing from Outer Space. They can also be found at the Overthere Stair and in the Flipside Pit of 100 Trials (rooms 61 and 76).

Beepboxers like loud music, and attack by shooting sound waves at Mario and his allies. Like their relatives, Beepboxers have high HP. Strangely, they can't stand explosions: detonating Boomer will stun all Beepboxers on the screen, even if they are not directly caught in the explosion.
