In Luigi's Mansion, there is a task that you can decide whether to accomplish or not: to catch all the 50 hiding Boos. I am trying to catch all 50 Boos, but I don't want to waste my time on something that might have a simple ending. So, what happens when someone catches all 50 Boos?

1 Answer

When you vacuum up the very last Boo, it drops a Gold Diamond, for 20 000 000 G (more than the value of any other collectible).
