Parfay and Sorbey were both part of a program made for the purpose of introducing a possible "friend" for children and the sort to interact with, titled: "Project Slushmate". A profit was sure to be made. Unfortunately, this program didn't last very long, as the slime-based beings were to proven to be very mischievous and caused a lot of trouble. The slimes were immediately recalled after these incidents. Parfay and Sorbey were the two slimes that were able to escape the recall and are possibly the last left of their kind. This isn't the end for the slimes though! These creatures were all artificially created, so creating more shouldn't be a problem, right?

Sorbey is pomegranate-flavored and Parfay is blueberry-flavored. For those who wanted to know. :P
