Heidi Shadows is a secret ninja in The Sims Bustin' Out and The Urbz: Sims in the City on Game Boy Advance and Nintendo DS. She sells different kinds of berries that can add up your skill points. She also sells a slip of paper that says "bucket" and flowers when bought will give the player a hefty sum of money (§5,000 in Bustin' Out, §2,222 in The Urbz). She also triggers one of the missions in Chapter 5 of The Urbz, so beware. Her name is a pun on "hiding in the shadows", a stereotypical ninja behavior.
