Of course, it is not recommended that there are more than one person inside the ball. The player can walk, run, or do some other tricks inside the ball on the water, as long as there is not any sharp thing inside to cut the ball open. Besides that, the water walking ball is totally waterproof, which also means that the player have to get out of the water 15-20 minutes to refresh the air.
