Blaino (Link's Awakening)

Blaino is the mini-boss of Turtle Rock, the eighth and final dungeon in The Legend of Zelda: Link's Awakening. He is a short, stocky penguin-like monster who likes to box.

Strategy
In order to defeat this "fierce" little guy, you've gotta time your Spin Attack very well. When he lets his guard down, which may signify him charging up for a punch, use Roc's Feather and release the Spin Attack right over him. This will result in damage. Many other weapons work as well. After he's taken several sword strikes, he will be defeated.
