There's a dark forest next to the kingdom. It's darkness... It scares you a bit.

The more you go forward, the more you hear ghosts sounds.

You continue to proceed walking until you find a mansion, a abandoned mansion. Who even lives there?

The doors open by themselves, You manage to get in, but now there's no way out. Just until you find...

Luigi. With his PolterGust 3000 (Some type of Ghost sucking machine or weapon.)

" O-Oh? You also got trapped in here too? " Luigi asked, where you can clearly see he's also scared.
