In this video, I show you how to obtain all the Electoons and the Lum Medal for the "Don't Shoot the DJ" level of "The Grumbling Grottos".
I'm sure you don't need me to tell you, but this level is fucking hard. Mere survival is not that bad, but getting the Lum Medal means you seriously need to be bringing your A game if you want to succeed with just one player. It makes me wonder if anyone bothered to playtest the subworld Moskito levels in single-player.
I'll confess that it's possible to get some of the Lums that I missed in this video, but it was difficult enough getting this result, so I sure as hell am not going back to make a better run. Feel free to do so yourself if you want something even more crazy hard.
