Sally Seal is as her name implies a seal.  She is soft and caring. She loves teaching, and protecting wildlife, and the environment. And she will become very irritable if her teachings are ignored, and what she protects is tarnished. Though her hacked self is a cruel, and mostly unfeeling manipulator. Often being very manic, possibly like Twizzly Gummy Cookie. Though her true self often comes out around characters like Poinette. Taking time to comfort her, and show her around. As I'd imagine she's the only one who feels bad for her in their location. I imagine her to have a high pitched and semi raspy voice. Maybe like Rainbow Dash with less raspy, combined with Ursula or Dot Warner
