Walt Disney's Mickey Mouse and Friends #287

Mickey Mouse and Goofy embark on a wild underwater adventure when Goofy’s latest invention—a tank that can both fly and dive—leads them to a hidden world beneath the sea. Inside a vast air-filled cavern, they discover a thriving city and a mysterious king, only to find their vehicle stolen by the elusive Count Drakova, who’s made it vanish without a trace. Now, with the fate of the city’s ruler hanging in the balance, Mickey and Goofy must track down the invisible tank and confront the villain before he claims his prize.

Mickey Mouse sets out to impress Minnie by turning his backyard into a bird sanctuary, complete with a special power feed meant to make the birds sing beautifully. But when the treat goes awry, the feathered friends grow far bigger than expected—leaving Mickey, Pluto, and Minnie to deal with the surprising consequences of their feathered guests' sudden size.
