Biography
He is a penguin who competed against the famous surfer Big Z during a surfing contest on Pen Gu Island. During the surf off, Tank wiped Big Z out. Tired and knowing that he couldn't compete against Tank, Big Z faked a disappearance. Following this, a surfing contest called "The Big Z Memorial Surf Off" started and was won by Tank nine times.

Ten years after Big Z's disappearance, Tank returned to Pen Gu Island to take part in the tenth surf off. Whilst on the island, Tank disrespects Big Z's memorial, much to the disgust and anger of fellow participate and fan of Big Z Cody Maverick, who challenges Tank to a surf off. Tank wins the surf off by wiping out Cody, who,is rescued by Pen Gu Island's lifeguard Lani, who takes him to be healed by her uncle Geek (who is actually an older Big Z).

On the day of the surf off, Tank competes against Cody and Chicken Joe. Tank tries to knock Chicken Joe off his board, but is stopped by Cody. Tank and Cody end up in an area of the sea called The Boneyard (which had killed surfers in the past). Tank knocks Cody off his board, but ends up crashing. Lani helps Tank back to shore whilst Big Z comes to Cody's aid.

Afterwards Tank is disqualified from the surf off.
