Luigi's Mansion Walkthrough Part 5: Boo Hunting

I finally get into the mechanic of Boo Collecting. It's pretty easy to explain and do though. So, I won't burn a lot of time doing so. But, I do have to go back into cleared rooms to track the critters down. It's all for that A-rank in the end! :D

Also, this part is extra-long by accident. But, this video upload just happened to fall on Christmas, so consider it accidental Christmas Bonus footage, lol! Mid-upload edit: However, it's taking ages to upload.
*Snarly Teeth!* "RRRRRR!"

Enjoy!
