Commit 3: Created watching penguins

I had a lot of fun creating the animation of walking penguins. I initially didn't understand how the frames worked
but reading the source code helped me a lot. While creating an animation I realized that I needed to
edit my static drawing functions. I still need to edit them to firther my animation. For some strange reason when running my animation,
i get the background and i need to hit enter before the animation starts playing. I don't understand why this occurs.
Is it something I did or is that just how it runs?

Commit 1: Created a static image of a penguin on an iceberg
I was struggling how to draw an oval for my penguin. I needed to look
up videos/read up how to do it. I also had to look up how to set the size of the image.
I found it really difficult to just start the penguin, but once I got the shapes
I felt more comfortable.
Commit 2: Created an iteration of penguins
Created a function penguins which iterates the drawing of the penguin until the end of the screen.
I needed to do some debugging for this to work, I managed to solve it, but I don't know how I fixed the issue. For some strange reason it's drawing the first penguin twice and I don't know why. I need to figure that out. This part was much easier than drawing out the shapes.
