Use oddly curved V-shapes to form fenders for each outer wheel. For the other fender, start with a V-shape. To its ends add lines that curve up, to your left, and then down.
Add ovals for the eyes. Draw a curved line for the smile. Place a tube with rounded ends on top of a tube with pointed odd-shaped ends.
Through the bottom of the lower tube place a curved U-shape that is upside down and has its open end covered by a line.
