Bachelor is a member of the Brothers Bear. His only appearance is in the Game Boy Advance version of Donkey Kong Country 3: Dixie Kong's Double Trouble! in Lake Orangatanga, replacing Barnacle.
As his name implies, he is unmarried (which was presumably about to change) and lives in a bachelor pad on an island in the middle of Lake Orangatanga. After Doorstop Dash has been cleared, Dixie and Kiddy can swim to the island.
Bachelor is eager for his upcoming date, but he needs a Rose and a Box of Chocolates for the date. He gives the Kongs a Flupperius Petallus Pongus on their first visit, which is useless to him, but not to the Kongs; Bramble, upon seeing the pongus, gives them the Rose. As for the Box of Chocolates, they can be bought from Bazaar for twenty Bear Coins. As a reward for their efforts, Bachelor finally gives them a Banana Bird he'd been keeping as a pet.
Any details about the date or what happened during it is unknown.
