In this video, I cover getting all the Teensies and Cups for the "Mansion of the Deep" level of "20,000 Lums Under the Sea".
0:19 - You can freely choose to go left or right first since you'll eventually have to do both areas in order to get to the level exit, but I feel that the right side is a little easier.
1:26 - Since the floor is slippery and since the beams are not very big, you can just run or slide past the beams even if they are aiming straight at you. However, there are various things up top, so it doesn't make too much sense to skip them by sticking to the bottom. As a side note, Ursula has a fairly unique means of gliding compared to most other characters.
2:48 - It is technically possible to slip between two jellyfish, but it's not easy so you are better off just sticking to passing between undulations.
3:40 - Love this music. Reminds me a bit of Spy Hunter.
4:09 - Pretty clear Splinter Cell and Sam Fischer reference. The sound effect is just so damn iconic.
6:02 - Not a lot of extra lums, and again, I think I played just about perfectly in terms of lum collection.
