The Skinner Boys S01E24 - Blood Blossom

While camping, Charles and Tara stumble on the fearsome Venorok. The only way to stop is to put it to sleep with the scent of the Blood Blossom. Luckily Augustus Skinner stored a seed in the attic, but when Edward and Henry plant it, the Blood Blossom grows at an alarming rate, takes over the mansion and traps Julia & Wellington.
