Tempsy used to be a high school girl until she was kidnapped by scientists and became a half octopus and half girl creature. From the experiment of her becoming a monster, she speaks and behaves like a 2-3 year old toddler normally, but when she's angry, she talks in a full sentence. When she gains someone's trust, she would hug the person with her tentacle arms and never let the person go. She has a mouth on her stomach aswell. She doesn't like rainbows because the bright colors hurt her eyes.
