Phlegma appeared only several amount of times in the film. The first time was in the opening sceneduring the Dragon raid, yelling at Hiccup when she ran past him to fight the dragons, on his way to the blacksmith shop. The second time was in the great hall scene when Stoick discussed about looking for the dragon's nest one more time before the ice set in. She is later seen greeting Stoick after his unsuccessful attempt to find the Dragons' Nest, congratulating him for Hiccup's skill in Dragon Training. She later joins Stoick and the other vikings in the attack on the dragons' nest, and witnesses Hiccup's victory over the Red Death.
Phlegma was shown in the series Dragons: Riders of Berk and Defenders of Berk multiple times.
