Abstract: A hopping play ball comprises a pair of elongated grips or handles adjacent to each other and extending radially outward from the surface of the ball. The ball may also comprise an array of mammillated protrusions on the lower surface, opposite the handles, to improve the stability during bouncing on a soft or elastic surface, such as a trampoline rebounding mat. In other embodiments, the ball has one or more water reservoirs in fluid communication with squirt nozzles disposed on either the surface of the ball or an outward facing portion of the handles. The squirt nozzles are activated by the player via the handle grips, and may pump or squirt water in response to each bounce or may be triggered independent of the players bouncing movement. The mammillated surface aids in preventing slippage of the balls during such types of wet play with multiple players.
