A toy is for entertaining a user includes a shell portion configured to execute a play function, and at least one propulsion mechanism including a spring-loaded, directionally selectable propulsion member connected to the shell portion. The triggering object is optionally a play surface and the shell portion optionally includes a play ball having several of the propulsion mechanisms distributed over its surface for depressing and tilting by the user in individually selected directions into engagement with the shoulder engaging structure, so that projecting the ball against the play surface causes at least one of the projection members to contact the play surface and release the at least one projection member from engagement with its shoulder engaging structure, and so that the at least one projection member springs outwardly and delivers a propulsion member force against the play surface in a direction corresponding to the direction in which the projection member was tilted and the force combines with and alters the existing directional momentum of the play ball.
