No they're not gay, I just thought the audio was funny and fit them lol.

The little creatures at the end are Cúram, a species I made up. A little explanation about them since the video doesn't really explain it:

They're beings who feed off of love. However, they often mistake platonic love for romantic, and get veryyyy excited when they see any sort of vaguely romantic looking interaction happening. They're mostly friendly entities who don't usually do any harm and can just be quite annoying :3
