If he falls in the tub, he'll blame you for it.

Nautilator's potent Triple Crusher Cannon can crush even the toughest of alloys into a compact ball, and almost makes up for his clutzy performance. But for whatever reason, Piranacon isn't happy with mangling his victims into a ball, so he has Nautilator's Triple Crusher Cannon somehow turn into a heat-seeking Torpedo Cannon in Targetmaster mode. Nautilator probably blames Piranacon for not pulling the trigger correctly, or leaving the non-existent safety on when he jams.
