Mario's Bombs Away
The buddies first appear in Mario's Bombs Away, one in the left outpost and another one on the right side. The left one delivers bombs to Mario, and the right one throws the bombs to the enemy's base. When the player gets a miss, the bomb explodes into the left outpost, causing the left buddy to set on fire. The right one rarely takes out his hands for Mario to deliver the bomb.
