Background/History
Long time Friends of Sasha and Kole the three met during school.She would be picked on due to her fur color and name something that led to her temper issues.
Sasha and her Share a somewhat antagonistic friendship with Sasha loving to mess with her and make her angry. Specifically sending poor Frosty on "swirling trips" However the two share a bond and Frosty will often find elaborate ways to get back at Sasha.

Her and Kole have a much more mellow relationship often just relaxing or swapping the latest gaming or music news.

She's stayed close friend with the two due to the music shop Sasha runs called Swirling Records, a quiet little shop that she works in as a cashier. She also acts as the audio and sometimes camera woman or unwilling participant of Sasha's web shows being an unlucky victim often Flushed away by Sasha when the mood strikes her though she has returned the favor just as much sending the red panda spiraling on a trip through the pipes after knocking her for a loop. Thankfully Sasha does know several healing methods and knows he deserves the actions. Sasha is the only person she treats like this however and the two share an almost sister like bond.

When not working in the shop Frosty can normally be found relaxing at home in front of her computer listening to various bits of music, playing games, or working on audio mixing for Sasha with secret eagerness.
She shares her abode with a roommate who unfortunately also serves as a source of her anger since Bayah is particularly lazy and can often be found sleeping and lazing about their sometimes completely nude much to Frosty's embarrassment when she brings someone who does not know Bayah.
