Ep 2. Eye for an Eye

In the Danny Phantom season 3 episode 2 titled "Eye for an Eye," Danny struggles to keep his identity as a ghostly superhero a secret from his classmates while dealing with a new ghostly enemy. The episode starts with Danny's class visiting the Museum of Natural History, where Danny's crush, Valerie, is interning. While there, Danny discovers that one of the museum's exhibits, an ancient Egyptian sarcophagus, is emitting a ghostly aura. Danny transforms into his ghost form and investigates, only to find himself face to face with an angry ghost named Undergrowth.

Undergrowth is a powerful ghost who can control plants and use their energy to enhance his own abilities. He cast a spell over the sarcophagus and uses it to trap Danny. Undergrowth wants to take revenge on Danny for disrupting his attempts to take over the human world in an earlier episode. Danny tries to fight him off, but Undergrowth is too powerful for him. Eventually, his friends, Sam and Tucker, come to his rescue and help him escape from Undergrowth's grasp.

Danny manages to get away from Undergrowth, but not before the ghost infects him with a plant virus. Danny starts experiencing strange symptoms, including glowing green eyes and the ability to communicate with plants. Meanwhile, as Danny's alter-ego, Phantom, he is busy fighting off Undergrowth's plant minions, who are taking over the entire town.

As the ghostly battle rages on, Danny gets increasingly worried about his growing plant-like abilities. He realizes that if he doesn't find a cure soon, he might be stuck in this condition forever. Danny and his friends work tirelessly to find a cure. They consult books on plant-based magic, and Sam even goes to Valerie, who is also a skilled ghost hunter, for help.

Eventually, they come up with a plan to extract the virus from Danny's body by using a fresh sample of Undergrowth's plant magic. They lure Undergrowth into a trap and manage to extract the virus, curing Danny of his plant-like symptoms. However, the fight is not over yet. Undergrowth is still on the loose, and he is more powerful than ever.

In the final showdown, Danny and his friends team up with Valerie, who has developed a new weapon that can neutralize Undergrowth's powers. Together, they battle Undergrowth and manage to defeat him, saving the town from his wrath. The episode ends with Danny being grateful to his friends for their help and Valerie for her expertise in ghost hunting.

Overall, "Eye for an Eye" is an action-packed episode that showcases Danny's struggles as a teenage superhero and the challenges he faces in keeping his ghostly identity a secret.
