Bubbles are white and round and they are shot out of red cannons with a purple pipe. The cannons have a red ring. Underneath it is a purple ring and under neath that is pink circle with three yellow dots on it.
Bubbles appear being shot out of cannons. If Rockitty rockets into a bubble, Rockitty will stay in it floating in the air. When the bubble moves Rockitty will be carried with it. When the bubble pops, Rockitty will immediately jump out and bounce off anything it comes in contact. Bubbles are very useful to getting to other areas as well as sometimes proving annoying, sometimes making Rockitty get pushed back.
