Thread for random remarks and questions about Voynich images

I find it hard to interpret the object next to the frog in f101v1. On jasondavies.com it is totally hidden by the crease, but it is visible on the Beinecke scans. Since it is green, the obvious answer should be "a leaf" but, maybe because of the frog, I tend to see some kind of animal?
