The Sqawking Boomstick is an enemy in Mother 3. It is a strange sparrow-stick combination that also seems to have a bomb planted inside it. It self-destructs when necessary. It is related to the Squawking Stick.
Its battle sound is Battle Sound 27 which falls under Code Numbers 517 for regular attack, 518 for Smaaaash! and 519 for Miss. Using Kumatora's Brainshock is required to get him to use a physical attack as Squawking Boomstick only wastes a turn and explodes otherwise.
