So far I've been using scans of the official Linda³ artbook to access images of all the game's specimens. Whoever put the book together was insane for setting all the sprites against this dark background. During the compositing of this image, I found a screenshot of today's creacher in-game, and oh jeeves, I got the female panda's features wrong. I was really considering going back and redrawing the character to account for her extra legs.
Update: Edited the JP text.. It used to say ｢パンタ｣ ("panta") instead of ｢パンダ｣ ("panda")..
