Here's what the "cleaned up leg" sprite looks like, along with a single frame from both the running and sitting animations. As I mentioned before, I'm not really dead set on the color, so I've been playing around in that respect. Shown here are a few colors I decided to slap on just to see how they look. To be honest, they are all fairly decent. Some do fit better than others when you take into account the game's tilesets. In fact, I could see myself using certain color Oller for different areas in the game world. For example, they could choose to inhabit areas where they can easily blend in with the background. This is the sort of backstory/reasoning that would never be explicitly explained to the user. It could be one of those perks that only the very diligent and observant would pick up on.
Apart from all the art recently I've been extending the Oller's AI to perform arbitrary actions much like the Flowrian. Currently the Oller will either stand idling, walk around, or decide to take a break and sit down. This is another one of those NPCs that I don't want falling off ledges, so it's probably time to move that Flowrian specific code up the object chain and into the NPC base class.
