While the boss itself does not have any real attacks, it can only be attacked when it jumps out of the water. It will select a random location in the water, jump out from there, and then hang in the air for a second before dropping back into the water. It can appear anywhere between the two side platforms of the arena. The boss will be defeated after three hits.
To attack Robbie, the player has to wait above the water and then Drop onto his head while he is jumping. However, since there is water covering the bottom of the stage, the player must be careful to either bounce back up into their Dropped Balloons or onto one of the side platforms.
