Yama is a typical teen-mouse; he’s obsessed with Sumo wrestling, and hates working at his Uncle Herbie’s barber shop. He wishes he was someone else, someone special, someone who could make a difference… When Yama’s Uncle is kidnapped by the goons of Hieronymus Claw, the most powerful cat in Catropolis, Yama vows to find him. What he finds instead is his destiny, in the unlikely shape of an ancient o-icho, a sumo top knot, hidden in his uncle’s things, which has been in his family since ancient times.
During episode one, That’s A Big Mouse, Yama and his Aunty Dott return to the barber shop to find the place has been ransacked and his Uncle Herbie has mysteriously vanished. Yama vows to look after his Aunty Dott and find his Uncle Herbie.
While cleaning up the shop, Yama discovers a small wooden box with a strange insignia carved on the lid. Yama is amazed by what he finds – a strange sumo wrestler’s wig inside – an o-icho. Curious, Yama tries it on for size, but the second the wig touches his scalp, his body is transformed into a mountain of mousecular mayhem, the legendary avenger, Sumo Mouse.
Now, Yama must come to terms with his new found powers, restore the ancient balance, find his Uncle Herbie and defeat the evil of Claw – and maybe even find the courage to ask a girl out.
