Lisa Lionheart
Wikisimpsons - The Simpsons Wiki
Lisa Lionheart is a doll created by Lisa and Stacy Lovell. It was designed as competition for the Malibu Stacy line of dolls. When it was first released, all the young girls, as well as Waylon Smithers, were after it, but were literally intercepted in the store before they could reach the display of dolls by a cart of Talking Malibu Stacy dolls with new hats, leading to the complete failure of Lisa Lionheart.
Later, the Lisa Lionheart doll appears in the video game The Simpsons Hit & Run as a collector card in level 3.
