Epilogue:
Bob stayed with the Flock for many years, and grew up a very happy, well-rounded, intelligent unicorn. Iggy taught him about…well…pretty much everything. Fang taught him how to eat muffins (a VERY important aspect of unicorn training!) and Fang also taught him how best to wear skirts - in case he should need to costume himself sometime, of course! Gazzy taught him how to hotwire boats and be a persuasive talker, as well as how to play pranks on certain friends. Max taught him how to be a strong leader, and took charge of his physical training
Fang never touched another lemon-flavored muffin again (believing them to be evil, and deadly poison), and had nightmares about lemons for weeks on end..
Max didn't get much sleep for the next few weeks, having to console Fang on a nightly basis that no, the lemons weren't going to come and kill him...
No-one saw Iggy at all for the next few weeks - he was busy playing with the random equipment the unicorns had let him keep...
Gazzy was obliged to spend the next few weeks fishing, with the man whose boat he'd "borrowed", as compensation. Gazzy had protested the suggested arrangement, saying that he'd never really been fishing before...but this made the man all the more eager. He promised to teach Gazzy all about fishing - the equipment, the types of fish and where and when they were to be found, the local fishermen, the boat, the history of fishing…"There's a whole world you've not yet seen, me boy!" he had shouted, slapping a fish-stenched hand on Gazzy's back. Gazzy was NOT pleased.
So they all basically lived happily ever after. Except maybe Gazzy. But it was his own fault. And Fang, kinda, for a bit, but he was fine after a few days. And Iggy accidentally blew something up at some point, but…
Bob was very happy in his new environment.
The end.
