This Panda was created using Adobe Illustrator. I created it using many ellipses, rectangle tools, colored it with gradients and i made the grass and the supposed bamboo with the pen tool.

These 2 items were traced and filled in with color with adobe illustrator.

This is my Twitter bird that I traced using the pen tool in Adobe Illustrator.

This image was created on Adobe Illustrator. The main tools I used were the pen tool and the pencil tool, in fact those were pretty much the only ones. I also used the Gradient tool to give it the sunset look.
