Yoshi series[]
Super Mario World 2 Yoshi's Island[]
Co-Blargg first appears in Super Mario World 2 Yoshi's Island. They dwell in the lava waiting for Yoshi to get near them. When he does, they attack by leaping towards him. They can be defeated by throwing eggs at them but they reappear after a few seconds. The only way they can permanently defeated is the POW Block.
Yoshi's Island DS[]
Co-Blargg reappears in Yoshi's Island DS retaining their same attack pattern from Super Mario World 2 Yoshi's Island however this time, due to the removal of items, they are invincible.
Yoshi's New Island[]
Co-Blargg reappears in Yoshi's New Island, they once again use the same attack pattern from previous games. In this game, however, they are slightly larger.
