Zoo-Wee Mama!

Zoo-Wee-Mama is a comic strip from the Diary of a Wimpy Kid series. In its major role, it appears in the original book.

Greg Heffley created it, and then just lets his friend Rowley Jefferson take control of the operation. Pretty soon, though, Rowley says he has done everything that has to do with Zoo-Wee-Mama (In other words, he took credit for everything). Greg came up with the idea to make the characters say "Zoo-Wee-Mama" at the end of each strip, to avoid making punch lines. He let Rowley draw the panels. Greg did all of the writing and drawing. Rowley then complained he didn't get to do enough, so decided he could just take over. His versions lacked grammar, but it was enough for him to get class clown. Creighton the Cretin actually won the comic contest, but Mr. Ira changed the strips entirely, making Greg look like a teacher's pet. Furious, Greg quit and Zoo-Wee-Mama took it's place. Rowley quit drawing it in Rodrick Rules so he could spend more time playing with his Dinoblazer figures.

Trivia
In a flashback in the movie, unknown Zoo-Wee-Mama comic strips are shown. Extra stuff : (From The Movie 1)

The Zoo Wee Mama (in the movie) was made by Rowley himself when Greg got the idea of coming in the year book as the class clown (he fails but still he is in the yearbook with rowley as The Cutest Freinds). Greg leaves rowley to do the comic alone as he thinks that It is lame to say Zoo Wee Mama at the end of each Strip.
