Care Free Bombs, as per their name, only attack by throwing Bombs, and occasionally Super Bombs. They can be called into battle by the Loaded Dice, and regularly appear with a Mr. Molecule or another Care Free Bomb.
The Carefree Bomb's name and purpose is similar to the Mother 3 enemy Cuddle Bomb. Although they drastically differ in appearence, they both have bomb at the end of their names and are both formed from geometric shapes.
