What are these?

What do u think of these 2

The first one has some linear features and a possible eye feature going for it, the second looks very random, like a conglomerate of chewed sea shells. Hard to say intended figuration, not enough details, or nothing in my 'trigger memory' to give me a figurative interpretation.

The last one has quite a well defined eye shape, when looking at a small sized picture of it. From this, and with possible muzzle and mane interpretation, it could be a horse head figure, but also has a very bovine likeness, downward ear, upward horn to the right.
