The Many Faces of Rat Mason

According to the Interdimensional Rumor Mill, some things never change, even across dimensions. Someone, somewhere, decided to catalog all the different versions of Rat Mason in a Rumor Registry, but today the version from IF-14.662 is playing. Here’s what the rumors say...

Appearance as a Rat Piloting a Human-Sized Rat

Many have speculated that Mason is not actually the human-sized rat who goes by Rat Mason but instead is a rat who lives under his Blaseball cap and is, to quote social media, "piloting this [respectable] [fellow] Ratatouille-style." Tacos management has not confirmed this rumor due to a respect for Mason's privacy. When asked about these rumors, Manager Al Pastor said, "Sure we've never seen our boy Rat without his hat on, but we think it's like, totally chill if he's actually a rat who dreams of being a splorts star. Like they say: Anyone can Blaseball."

When pressed by reporters, an anonymous source who looks exactly like Mason but without a head had this to say: "Sure, I may or may not lose my free will to yanking on my hair while on the field, but hey; it sure is fun getting to play Blaseball in front of all those screaming fans".


Mason has missed the exit from the 405 to the 101 several times.

Mason reportedly wears jersey number 69.
