The creatures hub: They have great members in it like uberhaxornova slyfoxhound immortalhd and more they are all great. I suggest checking out their channels..great stuff.

Soclosetotoast

Sly is not in it anymore!

Kgo

Emma Blackery: she is a vlogger type person that I find hugely hilarious. She even did some things with nerdcubed

Ashens: he reviews cheap knockoffs and other shit and does it while continually amusing you.

Alphaomegasin: he talks about current gaming events.

Video game carnage: he is a commentater that isn't largely know but is funny in a bit of a vulgar way so watch out for that.

SSoHPKC: another member if the creatures, his sarcasm and general assholeness is great.
