In the game, you are a octopus and your mission is to defend your seabed from invading crabs, shrimps, squid and anemones. You can only squirt bubbles to drive away the invaders. During the game, you can collect the coins drop down from the sea and you can also use some energy to power-up yourself. Survive fifteen increasingly challenging waves before squaring off against the big boss!
Use the Arrow Keys or WASD Key to move around and jump. Use your mouse to aim. Click and hold your mouse button to shoot bubbles.
