Boomdineros are Bandineros with a Cannon-like armor that appear during the events of Wario Land: Shake It! If Wario even touches it, they would defend themselves with their shield hands. They attack by shooting cannonballs at Wario. If Wario performs an Earthshake Punch, he can stun the enemy, and pick it up. Then he can shake the armor off, revealing a regular red Bandinero. These enemies are also summoned by Bloomsday.

There are two varieties of Boomdineros: common silver ones and rare red ones. Silver ones shoot one spikeball at a time and take a while to react. However, red ones shoot spikeballs faster and react more quickly than silver ones.
