I’m glad you asked, new person who isn’t familiar with Infinity the Game. Here’s the quick answers:
• The aliens are called Tohaa, and they are one of several races of humanoid (surprise!) aliens from Infinity the Game. Maybe if aliens weren’t humanoid, aliens would be too weird. But if they weren’t weird aliens, they’d just be weird humans.
That sounds perfectly reasonable, you might say. And a bit trite, you might say, too, but hey—the Tohaa are selling well, and that’s good for the company. And I like the Tohaa, anyway.
• But what’s this business about artichokes?
Well you see, the weirdness that makes the Tohaa alien aliens instead of human aliens is the finny white artichoke, which is affixed to their head.
This head artichoke actually is very functional, as it’s their primary source of pheromonal release. They never need to comb their head leaves, because they’re fit and tight. The head artichoke is actually also how they talk, but more on that here.
• Finally, what’s with the orange pokey-headed guy? If you look at the picture above, there’s a rather orangey guy named “Sakiel Regiment“. The cartoon guy is one of those. I’m not sure what his orange pokey mohawk does, to be honest, but the Sakiel is one of the better pieces in the game—well, in the way that Rooks are better than Pawns in Chess.
• As for the “lonely” bit in Lonely Artichoke, that should be self-explanatory. ^.^
I hope this helps to answer those questions, and though the rest of the jokes on the comics may go over your head, thank you for visiting!
