Yeah, that's what I figured one day in the shower. No really, I was washing my hair thinking about my part in the series wondering, "Why Megamorphs? Hmm... wait... it would be a bummer if one person narrated everything like they do in the main series... and megamorphs are split between all the characters... oh it was a good move... I get it now." <-- my life story right there. Cool story bro.
Working on multiple books at once was also part of that train of thought. xD Like we narrate one book in one stage, then do the lines for other people's books in the next stage and so on. Once the "practise" is over there's more to flesh out. =P
