The I'm Tilly Tinker doll is a 10.75-inch (27 cm) interactive baby doll that crawls when the button on her back is pressed. She produces over 40 sounds, including excited crawling noises, eating sounds, and giggles, powered by 4 AA batteries (not included). The set includes a mess-free sippy cup that triggers munching sounds when placed in her mouth. A fluttering bee accessory is included—rolling it along the floor makes its wings move. The doll also features a 12-second musical mode activated by pressing and holding the button on her back, causing her arms and legs to wiggle. Her soft, brushable hair can be styled, and she wears a removable onesie. Designed for children ages 3 and up, this Baby Alive doll encourages imaginative play and nurturing skills.
