Boom Boos are almost identical to Booms, except that they are much larger and with bigger facial characteristics. They have round white bodies with small thin arm, sharp three-fingered hands, and two small sharp points on their bottom which resemble legs. They also have red and orange maniac eyes with black pupils and sharp black teeth. Calm Boom Boos however, have black and soulless eyes, a torn bottom, paper-like flaps for hands, and knitted-up mouths.
Chaos Emerald SagaEdit
Several Booms formed a Boom Boo to fight Amy Rose after the Booms and King Boom Boo's prisoners began fighting back after escaping. However, the Boom Boo was no match for Amy, who smacked it into a wall with her Piko Piko Hammer, knocking it senseless.
