The cruel seamonster has taken a baby dino captive on the small island, guarding the waters around the island voraciously. The dinosaurs walk around the board, collecting the watersteps needed to get out to the island and rescue baby dino. On the way you can meet both the sea monster that steals watersteps and the pterodactyl that can fly you to a location of your choice. If you meet another dinosaur you can challenge it for watersteps. The winner is the player that reaches the island first and and saves babydino. You start with placing the tiles on the board backside up, then take turns moving along the lines collecting waterstep tiles needed to save the baby dino, stone tiles are useless, landsteps are needed to cross certain sections.
