S02E12 Dr. Animo and the Mutant Ray

The Tennysons arrive at a swamp just in time for the Gatorfest celebrations happening the following day. Gwen spots Ben fiddling with the Omnitrix and cautions him about the potential chaos it could cause. Ignoring both Max and Gwen’s advice, he pops the face out, triggering the device to malfunction. Initially, everything seems fine, but trouble brews unnoticed until the next day. As Gatorfest kicks off, Dr. Animo’s giant frog crashes the festivities, seeking vengeance against Ben. When Ben transforms, he becomes a hybrid alien with unpredictable traits. Will he finally learn to heed warnings?
