well making him was easy. just needed to make circles, the shape, lines, and finally filling them with red. the smile over there is a half pepperoni as I see pepperoni in pizza being half instead of full.
how I made a half pepperoni:
type in the letter D then tilt the letter 90 degrees. making it a smiley face. then fill it's open spot with the color red. or if you prefer, draw it till it's filled red.
how I made perfect circles and a perfect body:
you'll know if you visit paint 3D and go to the 2D shapes option.
