Mickey and Donald take Goofy to Idaho to visit a potato-themed theme park called "Potatoland". However, when Mickey and Donald discover that Potatoland is just part of a sign that introduces people into Idaho, they attempt to make Goofy's dream come true by building a Disneyland-style theme park, complete with carousel, Haunted Mansion and Great Moments with Mr. Lincoln, made of gravy and potatoes.
