Halloweentown High
Marnie is at a high school where some of her fellow pupils are magical creatures, including Natalie the pink troll (Olesya Rulin), disguising themselves and trying to fit in as normal high school students.
When she’s in disguise Natalie really looks like Kelsi, the pianist in High School Musical. Okay, I know that trolls would normally be classified with goblins rather than elves, but there is, as they say, ‘no harm in her’.
