In an attempt to convince Minnie that he hasn't forgotten to buy her an anniversary present, Mickey Mouse ends up promising to take her to Hawaii. Funds being short, he applies for a job as lab assistant to the sinister Dr. Frankenollie, who happens to be searching for a donor to provide his monstrous creation with a brain.
Unfortunately the movie Runaway Brain is not yet available on HBO Max.
