22 year old leopard gecko

This is my older brother’s 22 year old leopard gecko. Her name is Ridley, and she’s a normal morph and mack snow morph mix! She is quite friendly! Unfortunately, she is a bit overweight, so I need to convince my brother to feed her a bit less! (Before anyone comments anything, I am aware of the stuck shed on one of her toes, I sprayed her humid hide to ensure that she gets it off!)
