Several pairs of valves and nozzles are provided around the outer periphery of the toy between the platform and base with each valve positioned to be contacted by and depressed by the platform as the platform pivots onto such valve.

When the platform is stepped on within an area surrounded by the pivot members and with sufficient force, the platform is depressed vertically and all four valves are depressed and open. A simultaneous depression of all valves can be prevented by supporting the platform directly on the pivot members before activation.
