Probably seen this on the side bar now, but this is a larger image of the same. Enjoyed making this; the challenge was to get as many species as I could without it becoming cluttered when shrunk to sidebar size. For the curious, the reason for no yaks was the picture was completed before Party Pooped came out.
Why Cheerilee? I always imagined her as the tourist type, going on trips (mostly in the summer) to various places in Equestria, collecting images and souvenirs for herself and for future school lessons.
