Lost fluffy light brown and white guinea pig named Nibbles who escaped from backyard playpen in Southern WV.

I lost my guinea pig, named Nibbles, while I was out in my backyard in Southern WV. He escaped from his playpen yesterday evening, and I've been searching all over the neighborhood since then. He's a fluffy, light brown and white critter, super friendly but a bit skittish. If anyone sees him, please let me know. I'm really worried about him!
