You find yourself in an underwater seascape, starting with nothing but a hand full of cards. They have strange creatures called "Flubbies" on them. Play the cards to create a Flubby. Likewise, the Flubby starts with nothing - it can't swim very well, has no mouth, no shell, no Flubby-Friends. With more cards you can change that! Grow your Flubbies to their full potential and create your Flubby Farm! Beware though, as you are not alone with your Flubbies... A rivaling swarm of aggressive Gronkas is already on their way! How long can you maintain your Flubby Farm against the ever-growing Gronka group?
