An act of entering a body of water head first allowing the rest of the body to collapse into the water with a splash. May be used to enter a deep body of water with a steep bank.
A play approaches a water hole where two males are playing. He studies them and then chooses a place a bit further on to enter the water hole. He takes a step into the water onto what appears to be a small ledge and then Plunges headfirst into the water allowing his body and hind legs to collapse into the water with a big splash.
