Help! I'm trapped in a vampire's body

Jake's nervous when the DITS malfunctions near Vlad, a creepy new custodian. There's no way he wants this guy's body. But nothing happens ... until nighttime, when Jake finds he's turned into a vampire! With his fangs, he scares the kids who crash his Halloween party. But the next day Jake still looks like Vlad. Thanks to sunblock SPF 45, Jake can go to school. But there's no way he can get Vlad to take back his body. And if Vlad won't, who will?
