I've begun work on a short cartoon starring Koko and Marl, with a brief cameo of Jodo. I started working on layouts, which are mostly done, and I have Koko and Jodo's voices recorded; I just need Marl's and I'm pretty much set for animating.
In case you're wondering, Koko and Jodo are both voiced by Kyle Carrozza. Yes, Koko is voiced by a man. Kyle sent his recording of Koko in as a half-joke (he auditioned for the male characters), but his take ended up being the closest to what I was looking for.
