Her description by her player, you know the drill.

Chunky is a very large pony, large not even covering all of it. Her coat is a nice light pink, nice groomed and soft to the touch. Her mane is wavy. She has it cut shoulder length, to prevent it from getting stuck in food and in her fat rolls. Her eyes are a light hazel color, and sparkle with what looks like glints of gold.. She is an average pony when it comes to height. When it comes to weight, she takes the cake (quite literally)

She is a very very obese mare. Her legs have rolls of fat hanging off of them, sort of over laping her knees. Her back thighs rub together. Her stomach hangs very low to the floor. As she walks, it sways side-to-side and occasionally bounces off of the floor. Her butt if very big. Deliciously round with a hint of cellulite. Stretch marks marr the insides of her legs and the bottom of her belly, a darker pink then her fur. Her face is very chubby, her cheeks coated in a constant state of light blush.
