I remember the deer creatures that hang around the satyr you can fight are still a silhouette, and so are the ragroaches. I do think that having some art or icons for the animals you can adopt would be cool too.
I did forget about the stags since you rarely see them, unless you're grinding satyrs for some reason. Ragroach, I'm unsure whether that can be considered early... I guess so, since it's possible to encounter them fairly early, long before defeating them consistently is actually feasible.
