Ronnie Bergstedt

Ronnie Bergstedt is a scout boy and is in Ms. Vanthrax's classroom and a close friend of Ginger. He has curly brown hair and wears glasses. In "Cheat Code", he reveals that he is Builder X, an elite SquareStack player.

Appearance
Ronnie is an eccentric, geeky kid with large, round-rimmed glasses and a scout uniform that he wears everywhere.

Personality
Besides the time when he stole Ginger's science fair project, he is seen to be quite nice to the friends, being friends with Ginger in particular.

Still, he is quite wimpy, often cracking under pressure and shying away from danger. For example, during a father-son beanbag contest, he hid in a barrel while his father fought for him.
