The episode begins from the dragon's point of view. The baby dracos is running from the Troop when it encounters Phoebe, who is supposed to be waiting for her older brother Jake to pick her up. Phoebe, thinking the Dracos is a baby lizard, adopts it as her pet, naming it Sam and dressing it up in a dress. Things go awry when Sam begins to mature and burns almost everything in her room. The Troop finds the dragon and takes it back the HQ, but Phoebe learns their secret (she's snarked at the end of the episode). The Troop must take Sam back the portal so he can get back into his own dimension- all while Sam's mother is out to find her baby.
It was a cute idea, but Phoebe's acting seems a little forced. I love the baby dragon, and the last scene adds a little suspense, but, again, the Phoebe's part just doesn't flow.
