Raccoon

The Tanooki are a race of rather plump raccoon-like canines, found primarily on Isle Delfino. Though only three are shown, it appears that Tanookis work as vendors for a living and the race itself does not appear to populate Isle Delfino in as large numbers as the other races, such as Piantas and Nokis.

Super Mario Sunshine
In Super Mario Sunshine, the Boathouse in Delfino Plaza is run by two Tanooki, one older and one younger. Additionally, another Tanooki owns a small rowboat shack in Noki Bay. According to a sign near the shop, the boats can be rented for 90,000 coins, though the owner states that Mario is allowed to use them for free.

Super Paper Mario
In Super Paper Mario, the character Francis mentions that he would like a Tanooki Suit made with real Tanooki fur.

Trivia

 * The Tanooki are actually based on an animal known in Japan as tanuki, or in English as the Japanese raccoon dog. It is often said to be a shape-shifting trickster in Japanese folklore.
 * The design of Tanookis from Super Mario Sunshine was likely modeled after the Tanuki Statues all across Japan; the sun hat, shirt/coat, tail, and sash are all trademarks of the statues.
