Nightmare Fuel / Trollz

• Snarf's first appearance is pretty frightening, as he's seen only in silhouette. The girls have no idea who or what he is, but they know he's bad news. His first transformation into an ogre is scary, too.
• Simon's possession of Topaz. She's seen fighting from the inside by banging on her own eye, and her mindscape is a yellow void filled with swirls.
• The walking trees in "The Big Test" capture Ruby and even scare the girls.
  Topaz: If Mr. Trollheimer taught us about walking trees, I was absent that day!
• In "Field Trip" the girls and boys are attacked by ghost dogs when the bus breaks down. The dogs, being ghosts, are intangible enough to phase through walls, but can still eat them.
• When Simon tries to turn Onyx into a tree, he at first simply imprisons her within one. Eventually she'd become part of the tree, like what happened with Zirconia.
• The Trollz turning evil in "When Good Girls Go Bad". The scare factor is really ramped up when they freeze Coral, Opal, and Jade with a spell and manipulate them like puppets, and kind, sweet Amethyst tends to get the most disturbing lines.
  Amethyst: I know it's wrong to use magic to do bad things... But I just can't seem to help myself anymore.
