She grows after bart's Prank.
What was Bart's prank
My guess is the bart use some science stuff from the school lab, turn it what HE'S believe is a stink bomb, use it on lisa, and ta-da! Turning her into what soon to be a 50 to 100-feet-tall, neked 8 year old girl.
I have no friggin idea
She must get her dresses and panties at the same store the Incredible Hulk gets his pants!
I love giant Lisa. More of this kind, please!
I love this pic, Lisa giantess is the best! thank you
Shoot she could've made a fortune if those pearls grew a little bigger.
