Luigi's Mansion 3 100% Walkthrough Part 19 - Final Boss and Ending

This is the 19th and final part of my 100% walkthrough of Luigi's Mansion 3 on the Switch. This video shows how to defeat King Boo on top of the Last Resort and rescue E. Gadd, the Toads, Mario and Princess Peach. This video also shows the end cutscenes and credits. This video is made for educational purposes. I do not own the rights to this game, but I do add my editing and creative input. All gameplay footage is my own. #luigismansion3 #nintendoswitch
