Box of Chocolates
From the Super Mario Wiki
The Box of Chocolates is an item that only appears in the Game Boy Advance port of Donkey Kong Country 3: Dixie Kong's Double Trouble!
At his pad in Lake Orangatanga, Bachelor tells the Kongs that he needs a Box of Chocolates and a Rose for his "hot date". The Kongs can obtain the Box of Chocolates by purchasing it at Bazaar's General Store for twenty Bear Coins. When Dixie and Kiddy Kong give both items to Bachelor, he rewards the Kongs with a Banana Bird, which he had offered earlier.
