Sewing an interactive pillow

One college of mine is obsessed with frogs. But you know, in a good way.
She helps them on frog recues, takes pictures of them on hikes, reads about them, all that kind of stuff. And I always loved the passion in her when she talks about the different spieces and stories she knows.
Anyhow, I decided to saw her a soft and cozy pillow for her birthday by hand, and surprise her.
I collected parts of the frog from T-shirts, pijamas, different kinds of fabrics and I could finally finish sewing the parts together.
She got it today and I think she really liked it. :)

So, enjoy!
This is the front of the pillow.

And this is how you can open its mouth. :)
