Yatta is a crazy, generous, hyper, and loud toon, always putting her friends in a positive light and thinking "highly" of them. As seen in conversations with Astro and Teagan, Yatta is jittery and hates keeping still on top of being somewhat impatient, which is shown in one of her interactions with Connie. She also doesn't fall easily for tricks, as seen in Gigi's dialogue with her.

Additionally, Yatta is more attentive and clever than she initially appears, managing to pick up on an interest  Shelly has (outside of dinosaurs) from Tisha and bringing it up to her, or managing to turn one of  Shrimpo's insults back on him. However, her behavior can make other Toons concerned for her.
