Cassie is one of the six voices in Eevee's head she primarily likes to poke people and she is very impulsive and want's everyone to know it. She also is the only voice that can control Eevee's body but only his left hand. She is the only voice that publically known, through her blog that she types on his phone in Eevee's left hand and Eevee is fully unaware of this. She also owns many social media accounts. When it comes to her voice I am looking for a lower voice and always filled with some sass.
