Metal Eggdozer

A Metal Eggdozer is an item found in Yoshi's New Island. Yoshis can get Metal Eggdozers by swallowing a Metal Shy Guy and can use them to break walls or obstacles. When a Metal Eggdozer comes into contact with something unbreakable, it turns yellow and then goes the other way. If this happens one more time, it turns red and finally comes off screen after another hit. They are also essential in some boss battles and can also go underwater, where they are primarily used.
