There's no explanation for it either. He is NOT meant to be able to swim and is instead meant to sink like a stone! These comics clearly aren't canon.
I know he has water wings, but that wouldn't account for the extra weight of the scuba gear.
So far I'm 18 pages in. Takes place 6 years after the end of Homestuck.
I would post on Ao3, but I find the colour formatting so annoying to use.

She first appeared in Sittin' On a Backyard Fence and I think her last appearance was in Puss n' Booty. Funnily enough, both shorts were made nearly exactly 10 years apart.
So Humans seem to have regular blood.
Trolls blood colour depends on caste, but other than that it seems to be regular blood. I know different coloured blood in real world animals is due to different metals going around their bodies instead of red iron blood like ours. Additionally, the further up the caste you go, the more cold-blooded Trolls tend to be (according to Friendsim).
Not sure about Cherubs. Just seems to be regular blood but red or lime.
Satyrs on the other hand seem to have mercury blood. So it's the first time we know a species with poisonous blood.
Nymphs have "Onix" blood, though it looks more like ferrofluid.
I find it odd that these two newest species have unique blood properties that the other species do not. Especially since blood colour meant so much to Trolls... only for it to just be normal blood.
It's just so strange how little pink, orange and yellow get used compared to green, purple and blue.
Instead we get a side mode. There are already so many characters that there is nothing to do with in single player! Why add more? I know not much if known about the new mode, but from what I can tell, it looks like it's about an hour long max. At least BT2 and 3 side modes complemented the main story content, since you could use the stat boosts in all modes from what I recall.
Sparking Zero on the other hand just added a level system for one side mode that seems to be exclusive to it. Why bother? Why not instead revamp the already gutted story content to make it match up to even BT1?
