The bird is especially good, Marco, even though the texture is different, the shape is an excellent match for the general style of the outline.
I've collected countless bird drawings, looking for something similar, but I don't think any are as similar as the one you just posted.
Also, if you look at the snake in the fish's mouth, it is a snub-nosed serpent without ears, which is also somewhat hard to find, and there is one in the root in the small-plants section in the VMS. It's possible to find snub-nosed snakes, but they are not super common.
Also the fish has the right kind of tail and all-over scales, although I think the one you spotted in Sachsenspiegel might be a closer match overall.
