Sprout is a scientist, working on bringing his beloved best friend back to life. Sprout is a straightforward, overprotective, and pragmatic person. May also be pushy, but with good intentions. He can come off as uninterested when it comes to the Toons he isn't too comfortable with, but is more open and excitable to the people he is closer with, like with Cosmo. Sprout's bluntness and no-nonsense attitude may make him come off as stern, but at his core, he is very protective and caring.
