In the Adventure of Fish Gobbi you need to help a young and ambitious fish make it all the way to the top of the food chain in order to secure his place as the king of the ocean. However, being young, he has no idea how the sea world works, which is why he desperately needs your help. Contrarily to many fishing games, in the Adventure of Fish Gobbi you will first be presented with a menu where you can improve your character with points you gain during the course of the game by eating other fish smaller than yourself; beware of fish bigger than yourself, as they don't have any pity or quarter if you aren't too big for them. You simply need to use the mouse to swim around, guiding your fish, and to eat others you simply need to get close enough to them. Fish you cannot eat have a red aura around them to help you out.
