Walt Disney's Mickey Mouse

"When Mickey's best pal Goofy vanishes without a trace, even crazy Cousin Clabberwort can't find him... till he turns up in a government lab, packing a genious IQ and a pet pygmy cow! Just what does Mouseton's dippiest dawg--now known as 'Dr. X'--have in store for the world? Does Mickey dare find out? ... And 'Dr. X' is only the start! On beyond mad science, this climactic book of Gottfredson serials also finds Mickey plagued by Leavenworth Lee, the baby delinquent--and Gilhooley, the pitiless king of the leprechauns!"--Page 4 of cover.
