Earspeaker

Earspeakers (called headphones in North America and New Zealand) are a special effect first appearing in Super Marble Blast (also previously in Marble Blast II). They are carried by enemies and hazards, and the one that carries it is defeated/destroyed, they will drop to the ground and are able to be held. When activated by the player, it will muff any blast or missle and turn them into oil slicks.
