Stab or be stabbed!! Play as a deadly marine monster fish that stabs with a long tusk on its head. Choose to be a whale, shark, or dolphin. Move around using your mouse. Click and hold to boost. Collect food to boost. Kill your enemies and collect food to achieve a high score --which gets you a longer tusk!

The top 3 players of the day will get recognized and will be displayed. Will you make it to the hall of fame as top fish?
