One of the only cannonballs that sometimes results in a hate crime and usually jail time. A very technical cannonball that requires much skill and timing, it's a dangerous maneuver that requires the cannonballer to spot a person swimming harmlessly in the water, then shouting "dolphin cannonball" then doing a cannonball directly onto the swimmer sinking them to the bottom of the pool, like a dolphin who just blow holed your face. For the best results execute on small children and infants..
