Archaeologists Victoria Ventures and Tommy Garrison are in Asia to cross three Disneyland parks off their Bucket List. In this fourth installment of the Under The Magic Series, the spelunking couple flies to Hong Kong and checks into the Hollywood Hotel. After a big breakfast buffet at Chef Mickey's, they mistakenly ride a roller coaster—Big Grizzly Runaway Mine Cars. While waiting in line, they notice the rock formation hosting the ride is real. When the ride breaks down, Victoria jumps out of her mine car and vomits in an alcove. When Tommy jumps out to check on her, they discover a real mining cart on a separate set of tracks. Curiosity takes over and they jump into the cart, release the lever, and roll deep into and underground honeycombed with caves where they discover the find of a lifetime!
