Another great song from Selkione™! Tho the slime sounds feel a bit disconnected from the song, it`s also not that intrusive or out of place so it works!

Normally I save you for last, but since I am rating the different bosses in order (Pigeons - Gloo - Yuwall), you're next!

I was wondering what for interesting sounds you were going to pick for Gloo, and I love that it became these suction noises. Especially at 1:10+, they are soo delightfully gross xD (really, how did you make that?! Is that just an online sample?).
I read "I used a large orchestration", and I like that you kept that orchestration rather light to both show the big size as well as its derpy nature. That growl at 0:10 was nice too. Your sections nicely flow into one another, having a common theme but different instrumentation. The section from 0:55 onwards is quite different and really cool in its own right (including the delightful suction sounds).

And did you make that image yourself? I always imagined you used a combination of Photoshop with AI generated images to create your pics, but this seems hand-made, and well-made too!

In other words, just another banger of a track from my favorite composer :D

Love the sound effects and the use of a tambourine in the orchestration. The music already sounded great and little details like that added a lot!
