In Hey, That's My Fish!, players seek to catch as many fish as possible with their waddle of penguins. Each turn, players move 1 penguin in a straight line over hex-shaped ice tiles with 1, 2 or 3 fish on them. Players collect the hex from where the penguin began its movement from the table, creating a gap where penguins can't cross on future turns. When a penguin can't move, it's removed from the game with its owner claiming the tile it stands on. The player who gathers the most fish wins.
