Lab Rats Season 4 Episode 18

The Curse of the Screaming Skull

Leo just finishes his movie marathon while everyone else is frustrated because they have nothing to do on Halloween. Bob intentionally stays behind while the other students are away with Davenport to a museum. Perry says she's going to another island across from theirs, but Douglas says no because it's deserted and has been uninhabited for years. When Douglas leaves, the group decides to go anyway. While on the deserted island they come across a metal skull. Perry wants to bring with her to the academy, but Chase and Bree refuse to have it there and tells Perry to put it back. When everyone leaves, Perry sneaks the skull back to the academy. Meanwhile at the academy Adam teaches Bob about the art of Halloween but fails when Bob tells the others that Adam is trying to scare them with a skeleton. Perry paints the skull black and tries to sell it online. Leo, Bree, and Chase see this and Leo is immediately afraid saying everyone is cursed. Chase decides to take the skull back to the island despite Leo's paranoia. Bob tries to understand Halloween by showing Adam his most terrifying items such as a math test, a potato with eyes, and Santa Claus, but Adam is unimpressed. Perry runs into Bree and Leo saying that something is wrong. While trying to figure out what, a ceiling fan crashes down nearly killing them. Bree tries calm everyone down until a knives shoot across the room directly at Leo until he blocks it and a fireball hits Perry in the back of head, barely grazing her hair. Everyone is convinced that the skull is cursed and tells Bob and Adam, until Bob tells that everything was caused by Chase (with his skin turning pale and his eyes red). Bree decides to take it back to the island herself. Douglas arrives and tells him that skull is just a paperweight and virus was spilled on it and turns anyone evil for those who came into contact with it. Perry was uninfected when she touched it earlier because of the gloves she was wearing. Douglas decides to destroy it but can't because Bree left with it, and everyone sets out to find her, until she enters in the same condition as Chase. Bob is tied up when everyone returns, and Douglas uses Davenport's nanobots in the shape of an injector to cure Chase and Bree. Bree and Chase attempt to destroy everyone until Adam pretends to be infected to get close enough to cure Bree and Chase. With everyone cured, Douglas finally attempts to rebury the skull until Bob and Adam touch the skull.
