I drew a basic giant boy with a handful of guys telling them he will gobble them all up. Rather than draw a background, I found a suitable photo and pasted him in front of it-- a sort of drawing montage. Then I altered him to represent various other young giants, in various locations. Same guys, though. Maybe they clone them!
Anyway, as I think of other types, I'll add them later. Or any variations you might think up.
Now a giant dragon boy. He is sort of based on the character Pitch created by the artist MaxPitch, who posted on FurAffinity and deviantArt years ago. Alas, he closed his page, removed his art, and vanished. A pity. Pitch was a great character.
And he ate people when he was hungry. Dragons, you know.
If being swallowed by a giant demon boy means an eternity of torture as you are digested in the inferno of his belly, it's only logical that it must be a wonderful experience to be digested in a giant angel boy's stomach. Sounds good to me, anyway!
Another variation. Feel free to make suggestions!
For my next variant, we go to the steaming, hot depths of the jungle -- and this time these guys will soon be in the steaming, hot depths of the giant Jungle Boy! It does solve the mystery of Tarzan's recent disappearance, but it's clear these guys won't be telling anyone what they've learned. So their disappearance just adds another mystery to the jungle!
More variations on the them of a young giant offering to "Gobble you up"! We've ween a giant green alien, so how about a giant blue one -- a Na'vi, in this case. If you make an error in scale by this much -- well, a giant blue boy will give you a nice warm welcome in his nice warm belly.
Yet another variant -- a goo/slime/gel boy. He has gone to the trouble to form himself like a human and even made a sort of digestive system. Of course, as a slime-type creature, he could just absorb you through his outer skin, but I think he enjoys teasing his food, too!
