The Grinch Butt pattern makes exactly that! Place him against your Christmas tree to illustrate a favorite scene from the classic Grinch movie.
Your littles will light up at the sight of the Grinch in your tree.
-- OR-- change the colors and make it a Santa Bum! Or stripe the legs for an Elf bum!

Pattern was tested by multiple testers, and works up quickly!

worked mostly in Single crochet, with green, red and white yarn,
