Rockstar

Charles Entertainment "Rockstar" Cheese is a small mouse who likes to make people smile and be a little menace. People love him because he sings and dances and does a little jig, what a silly little guy, good for him.

Sales weren’t going well for CEC Entertainment so they thought if they redesigned Chuck E and his friends for the first time since 2005, they’d keep their restaurants contemporary with kids in the 21st century. In Summer 2012, a silhouette of the the redesigned character appeared on the official Chuck E. Cheese Facebook page, and was officially unveiled in July of that year. Chuck E. had an immediate switch with a new ad campaign for the summer, “Say Cheese It’s Funner”. This was the first time the character was presented in CGI in the promotional material, replacing the hand-drawn Avenger ads. The Duncan Brannan voice was switched to Jaret Reddick, the lead singer from the band Bowling For Soup. The redesign was initially met with backlash from fans and regular customers of Chuck E. Cheese’s. His personality changed again to be more like a Rockstar, and radical to the current generation of children. In the shows, he’s typically trying to do this his own way, but the other characters stop him from doing so, which causes him to rage. However he always tries to appeal to kids and take birthdays seriously.

Rockstar Chuck is, by far, the shortest version of the character, being the size of an actual rodent. A grey-furred mouse with green eyes, he usually wears a short-sleeved purple shirt with a large "C" print in the front and four green stripes shown underneath the print and on the sleeves and collar, similar to what Avenger Chuck wore. In addition, he also wears blue pants and red and white shoes. His whiskers and tail, which haven't been seen since the mid 1990s were brought back, although his tail is now black instead of pink.

Rockstar Chuck's original concept art depicted him in a long-sleeved yellow shirt with red stripes and a red "C" in the front along with brown pants, red shoes and he carried an orange guitar.

In a photograph that appeared in the song "Remember That Time" and the 40th anniversary version of "Together We've Got It", Rockstar Chuck wears the same tuxedo that Tux Chuck wore. The tuxedo has been slightly updated, as it now features black buttons instead of white, the dress shirt is now pleated at the bib, and the lapels and cummerbund now have a glittery gold mesh trim as opposed to the usual gold. In early promotional material for the character, Rockstar Chuck carried a black and white guitar. Interestingly, the guitar has the original 1979 PTT logo on the strap.
