What comic strip did Greg do in Diary of a Wimpy Kid with Rowley?

Greg doesn't actually draw a comic strip with Rowley in the "Diary of a Wimpy Kid" books. He does try to draw a comic strip, but it's not with Rowley.

In "Diary of a Wimpy Kid: Rodrick Rules," Greg attempts to create a comic strip called "Cheese Touch" about a boy who gets a mysterious "cheese touch" and is shunned by everyone. He even tries to get Rowley to star in it, but Rowley refuses because Greg doesn't want to draw him as the "cheese-touch" victim.
