Lupe Ontiveros' character

It's been a lil while since i seen it too but the parents go out to dinner so camille is watching the kids. its a typical rainy night and Dolly D calls jessica outside to the dollhouse and jessica goes. Camille goes outside to tell jessica to get back in the house, jessica acts as if she doesnt hear camille; So camille has to go out kinda far outside to grab her. the house door closes and they're locked out. the brother is upstairs with his walkman extra loud in his ears so he can't hear them knockin to get back inside, so camille tells jessica to wait and she goes to the cellar so she can get through the house im guessing. and down there she hears foot steps she thinks its jessica so she goes back to the cellar door to get out,its locked.She takes a seat on the steps and dolly d is awaitin under the steps. Dolly scares her and she falls down the steps. then alot of dolly runnin in the dark and finally she pushes camille or camille falls herself in this pool of water (i dont kno why water would b down there) and dolly d takes the light supply of the cellar pulls it down throws it in the water and camille is electrocuted.

Her surname was misspelled in the opening credits.
