You’ll pass a banner, some missing stones in the wall, another 2 banners, and a mysterious set of bricks. Shine your Dark Light on it to reveal a door.
Remove this banner from the wall and use the dark light to reveal a door. Inside is the gem.
Head through the door and you’ll enter the secret stash which will give you another gem and some serious coin.
How to Defeat Knight MacFright
Knight MacFright is ready to rumble but he doesn’t have many attacks. Here’s how you can defeat him.
Break his armor
Knight MacFright will loop around you (avoid him). When he charges towards you his head pop above his armor. Flash him with the Stobulb.
Flash Knight MacFright when he charges you. This will make him dizzy and leave him open for a suction shot.
Once you hit him with your light, he’ll retreat into his armor like a frightened turtle. Walk up to him and use your suction shot to vacuum and slam him.
Watch out for the arrows that will fire out of the back wall.
Repeat this 3 times and you’ll be able to face Knight MacFright head-on.
Capture MacFright
Similar to the chef boss from the Mezzanine, Knight MacFright will run and spin towards you.
Wait for him to tire himself out. His shield will get stuck in the ground for a second. Stun him with the Stobulb and vacuum him up.
When MacFright has his shield, use the suction shot or wait until he spins himself dizzy to stun and slam him.
Repeat this until he’s captured.
