The Baby Grangalan is an enemy in Crisis Core -Final Fantasy VII-. It is the smaller version of Grangalan Jr. spawned by the Grangalan Jr. itself.
This enemy is somewhat agile, so it will be a little difficult to land some critical attacks from its behind. Keep your distance from it, cast some Graviga, and finish it off with Assault Twister+. If you do not have Graviga, try using Iron Punch.
