Lab Bats is the second episode of Season 3 of Lab Rats, and is a Halloween episode.
It's Halloween, and all of the Davenports are watching scary movies. But when Adam is trying to scare his siblings, he accidently lets a bat in, and it destroys the lab. Everyone thinks it's just another one of Adam's pranks. But when the bat is hit by a special laser, it mutates into a real vampire! Can the Lab Rats defeat it before it "drinks zayr blood"?
