Shelly is an extroverted Toon, who enjoys talking about her interest in dinosaurs and other forms of prehistoric life, but she has other hobbies as well, such as sewing, which is shown in her dialogues with Bobette, Sprout, and Yatta. She is highly supportive and kind towards others, as hinted at through her Active Ability, possibly due to the influence of her Toon Handler or natural energy.
