The Ahnnabees is the clique Massie Block was a part of at her old school, PMS. The members were Ahnna (the alpha), Shauna, Lana, Brianna, and Massie. Massie was the only member in the group without a name without an "ahnna" sound, making her the odd one out of the clique.
The Ahnnabees are introduced in the Clique series prequel Charmed and Dangerous: The Rise of the Pretty Committee. It can be assumed that they are the second most prestigious clique at PMS, since Massie originally wanted to be in the clique, LMNOP, but couldn't join since there was already an "M" in the group. Massie had always thought that she didn't fit in, as Ahnna never considered any of her suggestions for the group and was not very friendly to her. At Merri-Lee Marvil's New Year's Yves Party, Massie meets Dylan Marvil, Alicia Rivera, and Kristen Gregory, and Massie ditches the Ahnnabees, transfers to Octavian County Day, and the Pretty Committee is formed.
