Hundreds of levels are no joke to you and they are waiting for you in the game UnderWater Bubbles. Pass them along the winding path and on each you must collect transparent air bubbles. Inside which the marine life is enclosed. To save them, you have to swap the positions of nearby standing bubbles in order to build a row of three or more identical ones. The scale at the top of the screen must be filled in completely for the level to be completed and you go to the next one in the UnderWater Bubbles game. The little octopus at the bottom of the screen will morally support you.
