Forest Creatures

I imagined a couple of creatures that would live in this post-apocaliptic environment. Since traditional fuels are no longer available and the world population was reduced drastically, the wild life had an oportunity to evolve without restrictions.

These forest creatures are mainly large, since they could profit from the florishing surroundings.

In  this piece we have the following:
Lagarllo: it can be foud from the size of a horse to the size of an elephant. they are omnivorous, and can eat fish as well as insects and plants. The human population in occations tame these creatures and use them as mount. They can be found in dense forests and jungles.
Ballerro: these are very friendly creatures that live in the shores. They eat small fish and crustaceans. whenever there is a human gathering, these curious creatures are the first to appear. They are a great companion for fishing villages. 
Picador común: These strange creatures live in the same environments as the Lagarllo. They are the sithe of a cat, and very unfriendly. They are rarely seen by humans. They eat mostly insects and sometimes fruits. Their peack allows them to reach the inner part of fallen logs, and feed from them.
