Mizuno Junko no Hansel & Gretel (2000)

Blurb:
Everyone knows Hansel and Gretel - Hansel’s the squatty kid with a tuna can strapped over his mouth to prevent it from shattering everything around him; Gretel’s the tall, pink-haired schoolgirl in the sailor suit, attacking bullies with her bamboo sword. At least that’s Junko Mizuno’s version! In this twisted take on the classic fairy tale, the kids' parents run the mountain grocery store, fielding visits from the green girls who grow spinach from their scalps and the 40-foot-tall piglet who slices cuts to order off his big belly. More madness comes with the arrival of Queen Marilyn and her insidious black magic! Can the kids save the day? This novel represents a new phase in Mizuno’s art, one marked by psychedelic hues that give the arresting story the feel of a dark dream. This tale from the master of the cute and the grotesque is color illustrated throughout.
