In this video, I show you how to obtain all the Electoons (except the time trial reward) and the Lum Medal for the "Golly G. Golem" level of "Mystical Pique".
You have my apologies for the many distracting splices in the video for this level. This is one of the harder levels in the game to collect everything, so I had to reset via death quite a bit in order to get this.
It's possible, though difficult, to acquire the Skull Coin at 1:57 by an alternative method. Instead of using the momentum from the recent wallrun, you can slide down the ledge nearby before hopping off and using that momentum (in conjunction with a careful glide) to safely get the difficult-to-reach Coin.
It's possible to get the Coin at 2:31 earlier, but I wanted to play it safe, so I waited for a later opportunity.
Make sure to use the ability to knock away lava balls to your advantage in the second alcove (the one with a minigame similar to Donkey Kong) as it's very difficult to succeed without injury by just running and jumping.
It's not necessary to stick around at the entrance of the boss chamber, but I did show to show off the slowly advancing tendrils.
We've seen a few boss battles before this level, but this is the first level where it's explicitly evident that a boss battle will serve as the climax.
In this video, I show you how to obtain the Time Trial Trophy for the "Golly G. Golem" level of "Mystical Pique".
In my opinion, the hardest part of this level is making it by all the throbbing tentacles in the second area. I don't have any advice other than practice makes perfect.
Depending on how fast or slow you make it through this level, the Psychlops at 1:17 will be at a different position. It was in a bad spot for me, but oftentimes it will be in the perfect spot to quickly run under to save some time.
