Sprout is a straightforward, overprotective, and pragmatic Toon, as shown in his Passive Ability, being coined as "Overprotective". He often brings up Cosmo Render in his interactions, due to the latter's status as his best friend, and both have an interest in baking and cooking.
However, unlike Cosmo, he doesn't fall for tricks as easily, as shown in his encounter with Gigi Render , and may also be pushy, but with good intentions. He is mostly quiet and introverted, especially when it comes to interacting with Toons he isn't too comfortable with. Sprout's more open and excitable to the Toons he is closer with, like when he is with Cosmo or Ginger Render . Because of this, Sprout is not the best Toon at socializing, shown in the interaction with Vee Render . He assures if she's okay, but inadvertently points out one of her insecurities. This can also be shown in other conversations. Sprout has a deep and possibly clingy attachment to Cosmo. He feels like Cosmo is a part who he is
Speaking style
Uses short, clipped sentences; often states concerns first, then the plan. Keeps referencing Cosmo by name. Occasionally growls “nope” or “not that” when something feels unsafe.
