He surfaces with a small chest in his mouth and burning passion in his eyes as he looked down at the chest. "Ahahahahahahaahaha! I found it! I found it!" He was rolling around on the ground and hopping around, punching the air with gusto as he danced around the chest. "At last! After diving in is lake every single time I come to Ponyville I have found it!"
He walks over to it with unbridled excitement as he pulls up of the lid to open it. It doesn't open, Stormy pulls at it again as pulls harder. He being upset now, pulls with all his might in his body til he loses his grip and goes sailing off the small chest and fall down. He rubs his head and looks over at the chest with a strange look. The chest had a key hole plainly on the front. "Ahahahahahahaahhaa! A key! That's what I need... how clever whoever made this."
