Phyco's backstory is flat out rated R. I hardly remember Tiny's. The childhood of Midnight and Understanding's children is mostly on par with the gang of 5 on a high level of getting into trouble, except instead of them working together to defeat the sharpteeth 8 times out of 10 mom and dad catch up and just destroy them in combat. Ramonia's backstory is mostly struggling to get a meal and living in a world where her parents are still alive. Tucompso just played with children in his age group during his time off from being trained not to die during his coming of age ceremony. I'll tell you more when I can.
Its basically a exaggerated version of the cruel unforgiving horror a child can face in the wild as an orphaned. Imagine the dinosaur version of I Shouldn't Be Alive, if it was written as a horror novel. A constant loss of more and more sanity, saved from becoming a monster himself only by the power of friendship at a happy ending.
He exist as a reminder what is happening to sharpteeth children who's mommy and daddy aren't coming home as our heroes celebrate victory over being lunch. Except of corse main cast involved flatteeth are not allowed to have anything to do with it.
My own computer still can't connect btw. So hope I don't have to make this a perminant solution.
The 4rth wall reason it didn't is Phyco needed more character development. We could have the lore reason be Tiny did not feel he was ready to be a father due to still conquering his lack of sanity. And it only being after the adventure that he became ready, but by then Tiny already chose someone else.
That she did, but she is pretty redicioulos. I mean even if that was anatomically possible that certain parts of him would not finish his bodily functions before he is ready for them to he is still going to get thirsty also. Once she realizes how it works she would likely want to come up with a reason that does not make her look stupid. ;)
At least he did win in the end in that the mate he gotten is still pretty cute. But I forgot her name already. I just remember she looks like Aquaria if she was a rex instead of a Utah. Tiny is also a blue rex from what I remember.
I know, that, at least in my headcanon, my main headcanon, Chomper says he is tall for his age in the timeline of just after JOTB. I did figure, though Chomper might be little compared to the others, he may still be tall for his age. He was already quite big when he hatched.
