Janet Esteves first set the Guinness World Record in 2006 when she had more than 2,100 Mickey Mouse items and has broken her record since then, the Orlando (Fla.) Sentinel reported Saturday.
"This is a passion," Esteves said. "Actually, it's an obsession. Some people think it's crazy, but frankly, I don't care."
The latest Guinness count put Esteves' collection at 4,127 items, but she says she actually has about 2,000 more pieces that have not yet been cataloged and counted.
Esteves, 57, keeps her collection, which includes plush dolls, pin and key-chain displays, and figurines, on display in her home in Celebration.
"I'm always looking for empty spaces on the walls and thinking, 'Which Mickey can I put there?'" Esteves said.
