"Check it out. Junior Plastics"
Junior Plastics are a trio of characters who appear briefly in the 2004 movie Mean Girls. They are portrayed by Megan Millington, Tara Shelley, and Shannon Todd.
The Junior Plastics attended North Shore High School. They are seen in the final scene walking together snobbishly. They look similar to Regina, Gretchen and Karen. Damian called them Junior Plastics, despite the fact that they were really freshmen.
Right before the movie ends, they get hit by a speeding bus as they are about to cross the street, which turned out to be Cady's imagination. As the movie ends, they are actually seen avoiding the bus and do not get run over.
The girls were only seen at the end of the movie.
