Character from Animal Crossing.
Tom Nook is a raccoon businessman who owns the main shop in your town and also deals in real estate. He is perhaps the most recognisable character of the series, even making cameos in other games and appearing as a trophy in Super Smash Bros. Melee. In both Animal Crossing games he sells wallpaper, flooring, furniture and tools. Nook also upgrades his shop after the player makes several transactions with him. He hires Timmy and Tommy, two raccoons that are believe to be related but are actually not , to help work at his store when upgraded to its final incarnation; a large department store called Nookington's. In the Japanese version of the games Nook is actually a Tanuki and indeed his name, Tom Nook sounds similar to Tanuki and his store's logo is that of the mythical leaf that Tanuki are said to be able to change objects into. The furniture Tom peddles also transforms into green leaves in a similar fashion for portability. He also will appear in the background of the stage Smashville in Super Smash Bros. Brawl.
In my opinion, Tom Nook is a cheap bastard. When you buy from him at full price, you can only get a 4th of the price when you sell it back to him. Second, he is a monopolizer in every animal crossing town. And lastly, I don't like him following me around the store when he is wearing that purple suit.
Tom Nook just upgraded his store to Nookington's. He must have bought out the competition.
