In this video, I show you how to obtain all the Electoons and the Lum Medal for the "It's a Jungle Out There..." level of "The Jibberish Jungle".
As seen in the video at 0:27, if you're really quick, you can get up to the platform with a Skull Coin and the Darktoon / Living Cage whilst the Darktoon isn't animating properly. It only lasts a few seconds, but it's an amusing oversight.
If you're observant, you might have noticed that I missed a few Lums that I could have otherwise collected with bit more finesse. Some levels are much less forgiving with their Medal requirements, but you can safely hit the 150 Lum mark even with a few errors here.
You don't need to lose your Heart to grab the Skull Coin right before the end of the level. It wasn't a major loss as the end was literally right there and because I was confidant that I'd surpass the Lum requirement even without it.
