Rat Mason is a Rat
Rat Mason, a small brown rat, grew up in New York City watching Blroadway productions and dreaming of becoming a professional dancer. His favourite play, The Nutcracker, inspired his hatred of legumes from an early point in life. Rat Mason moved to LA to pursue his dreams of living a flashier life and ended up residing in Hlollywood, where he also met his now-husband Penny. He cannot speak, but is able to write in and comprehend English, Spanish, and whatever language they speak in New York. Shortly after his arrival, Al Pastor tricked him into joining the Tacos by asking his name, and providing him a piece of "scrap paper" to write on which happened to be the Unlimited Tacos sign-up sheet. While his actual name appears to be Rathaniel, he insists that you can just call him Rat because "Rathaniel was [his] father's name".
While he has above-average intelligence and a strong affinity for Blaseball, he still desires food over anything and will frequently abandon bases, consequently getting tagged out for trying to chase the smell of tacos being prepared just outside of the stadium. He gets a lot of his food from attempting to steal from teammates, or from local taco trucks. Unfortunately for Rat, he is just as bad at stealing food as he is at stealing bases. His teammates will often give him food from their tacos anyway, because he is widely considered to be a lovable nuisance.
Rat bats with a normal-sized bat, which is very large for him. Because he is only a few inches tall, his teammates usually provide him with something like a stool or a stepladder to stand on while he bats. On one occasion, the team was unable to find something for him to stand on, leading Basilio Fig to volunteer to hold him up for the duration of the game.
