Mystical Cave

Background
When Nightlife City was founded back in 1957, the elder ordered them to find some more card jitsu cards (Due to Nightlife City having Card Jitsu card resources). As the penguins drilled, the caves opened up and a small lake was found, and a dojo was made. Then they started finding Card Jitsu Creatures that looked like little worms. After building a bridge to it, the Mystical Cave was complete.
