The Not-So-Itsy-Bitsy Spider (Night Frights, Bk. 3)

Twins Travis and Tara know something spooky and strange always happens in Wolver Hollow. But a night of popcorn, pizza, and watching Attack of the Space Lizards from Mars—for the hundredth time—with their never-off-the-phone babysitter, Rachel, turns into a night of terror when what appears to be a gigantic spider joins the party. But this creepy-crawly creature is in no mood to munch on popcorn: she has set her sights on some two-legged snacks!
