Pokemon Pikachu Sneakers/tennis shoes size 12

I am looking for a pair of boys "Pokemon Pikachu Sneaker's/tennis shoes? in a size 12. These are high top shoes. I live in a very small community and can not find them here. I see someone has a pair for sale but the are too small. I would like them to be in excellent conditon and at a resonable price. If anyone has these or know where I can find them would you so kindly let me know. These are for a very special little boy. Thanks! Ellen
