Index is a super helpful Luvalope. They know that Luvalopes are tough to draw, so they help people by posing and letting anyone draw them. The colors split where important changes happen in the design, and are all made to be easy to tell when something is going on.
Other than the artistic side, Index generally just hangs out around the place. They don't eat anything that had a cute face (Fish are UGLY apparently).
[artists note] Index okay to draw whenever you want practice for Luvalopes. The ones that are up for adoption aren't allowed to be drawn unless you own them. If you want to see what ones you CAN pick up, you can check them out here: https://www.weasyl.com/submissions?userid=14558&folderid=82092
