Continuing from season 14's ''The Coon Trilogy'', the boys are 10 years old and have entered the 5th grade, where Mr. Garrison is still teaching them. However, two Japanese girls have transferred to South Park Elementary in order to get the vaccine for the earthquake victims from Dr. Mephesto, who injects them with cat and rabbit DNA, which gives them superpowers. After saving Stan and Kyle from jumping off of a bridge due to a suicide pact, the girls become their new friends.

A short time later, Kenny can no longer handle the idea of his friends forgetting [[TheyKilledKenny that he died]], so [[Franchise/CthulhuMythos he summons Cthulhu to give powers to Stan, Kyle, Cartman, Wendy, and Butters]].

The fanfic was made by Tropers/CabbitGirlEmi. However, the story has long since been deleted from Fanfiction.Net.

-->'''Masako:''' No hard feelings, Nekagi-chan.
