Amy provided artwork for Boom! Studios' line of Disney comic books. Among them, she drew interior illustrations for the mini-series Muppet Peter Pan and Monsters, Inc.: Laugh Factory, as well as The Muppet Show Comic Book arc "Family Reunion". In addition to her work on these, she has illustrated several variant covers for The Muppet Show Comic Book, Muppet Robin Hood, Toy Story: Tales from the Toy Chest, Muppet King Arthur, Uncle Scrooge, Darkwing Duck, Mickey Mouse, Muppet Sherlock Holmes, and Donald Duck. After the cancellation of Boom!'s Muppet titles (and the eventual cancellation of their remaining Disney comics), Mebberson also illustrated some Muppet storybooks following the release of the 2011 Muppet film.
