In my headcannon for Chica (which will probably be used in my idea for a Sprout sitcom), Chica is kind and calm onscreen, while offscreen she is prone to throwing temper tantrums with the loudest screaming you've ever heard a lot. Luckily, Mrs. C (her mom) made her a list of strategies to calm herself down, which includes playing piano (which she's really good at) and meditating.
As of now, I'll be doing pictures of Sprout characters reacting to Chica's meltdowns. First up is Banjo from The Let's Go Show.
