The Scent of Blood: When a character takes damage from Tiger Shark's attack, you may mark that character. At the end of your turn, if Tiger Shark is within 3 squares of a character marked in this way but not adjacent, you may place him adjacent to that character.

Blood in the Water: Tiger Shark can use Charge. If Tiger Shark begins or ends a move action occupying water terrain, he can be given a close combat action as a free action after actions resolve.
