Oddsockeaters are small invisible sock thieves. They eat socks, but only one from each pair – the odd sock. We are introduced to the world of the Oddsockeaters through a small but brave hero called Hugo. The life of his grandpa Lamor, who raised him, is nearing its end and Hugo must leave their home and seek out his uncle Big Boss and two crazy cousins, who lives in the house of a their biggest adversary, a lonely professor. Hugo draws his courage from what his grandpa taught him – love toward family, good manners and the Oddsockeaters' ten commandments, and stick to it in his new home, even when he gets into scrapes by doing so.
