This is not Rio but it looks like an identical twin.
My grandma got new horses three weeks ago! They can be ridden and their names are Rio, the girl, and Ceasar, the boy. They can't make little horses. They dont get along well. Its like they split the feild and if one goes on the others side they charge and attack. That is a bad thing because their stalls are right next to each other and they bang on the stall door and sides to bite or attack each other. Rio is a paint and Ceasar is all black. Rio is a lot smaller then the giant Ceasar. They are my favorite horses ever and I got to go into Rio's stall! Ceasar is too big to go into his stall but me and Ceasar got to bond a LOT.
