Pixar has been heavily relying on the inner workings of a university to promote their upcoming Monsters, Inc. prequel Monsters University, and today’s preview is no different.

Yahoo! Movies premiered 7 Monsters University posters which offer easy overviews of the frats and sororities at the school.

Each of the posters, which look like pages out of the school’s yearbook, depicts the name of the group along with a photo of each member. Mike and Sulley are in the OK frat with four (or five if you count both heads on Terri and Terry) other members. “A collection of wholesome, good-natured misfits, the adorable brothers of Oozma Kappa (OK) have bonded over their inability to make it through the Scaring Program,” writes Disney. “With only four bodies in the house, they don’t even have enough members to compete in the Scare Games. What they lack in Scariness and self-confidence, they make up for in heart.”

The sorority PNK may be one of the more unique groups. “Pretty in pink, the sisters of Python Nu Kappa (PNK) are not to be underestimated. Led by their fearless queen bee Carrie, these ladies are smart, cold-hearted and merciless. Covered in pink from head to toe, the PNKs sweet exterior quickly turns terrifying when the Scare Games begin.”

Monsters, Inc. supporting characters are also present in these posters: Randall is in the RNR frat and George is in the JOX frat.

As you can tell, we’re going to be introduced to a ton of new characters throughout the film’s storyline.
