In this video, I show you how to obtain all the Electoons and the Lum Medal for the "Scuba Shootout" level of "The Angsty Abyss".
Considering how difficult some of the other subworld Moskito levels are, this one is comparatively easy. This is due in part to the comfortably large amount of extra Lums there are. I flub up a handful of opportunities for collecting Lums yet still end up way past the Medal quota.
1:58 - Close call, eh?
2:50 - 2:53 is a big part of my success in this recording since it allows you collect a hearty 65 Lums right before the end of the level.
