Bearjamin is a bear born as a fully grown bear who is aging backward into being a cub. One day while out in the woods foraging for berries he comes across a young woman named Hildegarde. The two instantly fall in love. Hildegarde's friends implore Hildegarde to break it off with Bearjamin as he seems to be aging backward, and he's a bear, but Hildegarde ignores her friends saying, "Love knows no age nor species." She also believes Bearjamin simply has a skin disease. Eventually Hildegarde realizes that Bearjamin is indeed a bear and leaves Bearjamin to move to Italy where, "no bear shall ever touch my heart again." Bearjamin wonders back into the woods, now a small cub, never to be seen again.
The main events of the novel take place in the summer of 1922. Nick Carraway, a Yale graduate takes a job in New York as a bond salesman. He rents a small house on Long Island in the (fictional) village of West Egg, next door to the lavish mansion of Jay Gatsbear, a mysterious millionaire who holds extravagant parties but does not participate in them. Nick eventually receives an invitation to one of Gatsbear's parties. Nick meets Gatsbear himself, an aloof and surprisingly young bear. Nick's friends try to warn him that Jay Gatsbear isn't a person at all, but rather a bear in human clothes. Nick refuses to believe his friends. Calamity and drinking ensues. There's a car crash... Gatsbear takes the blame for the wreck, and some people believe him because bears obviously can't drive, but then how does a bear fit into the car to begin with? Eventually a guy named George shoots Gatsbear.
