Would it be hard to learn how to make these?

I've always loved those little crocheted animals, but I don't know how to crochet. Would it be hard to learn and then learn to make the animals? Are the animals a lot more complicated? This is what they look like, a href="http://www.craftycrafty.tv/crochetcreatures.jpg." rel="nofollow"http://www.craftycrafty.tv/crochetcreatu…/a My gradma can crochet so I have someone to teach me, but she doesnt do the animals. So I would be on my own for that part. And what is the easiest one out there?
