Why? Because these unusual dolls have removable organs.
Designed for 4 to 12 year olds, Anatomic Anna and Andy are the brainchildren of a London-based homeschooling mother who wanted to further her kids' STEM education but could only find anatomical models made for medical students. So, she made her own.
Through her company, Little Boffins - Learn Through Play, she's kickstarting the two dolls. One doll, either male or female, costs £50 (about $64).
By the way, I couldn't help but notice that they resemble American Girl dolls. So, I checked their height. Like AG dolls, Anna and Andy also stand 18" tall. Given that, I'm guessing AG doll clothes will fit this gut-spilling duo too.
