Serving as Arthur's wizard in Camelot, Merlin has felt that his king has become full of hot air ever since he started his motivational speaking programs. When April, May, and June enter his tower, he becomes fascinated with the girl's smartphone and addicted to the games on it. Trying to get them to leave him alone, he lets them mess around with his magic spells, resulting in the girls accidentally summoning a dragon. As he's too absorbed in the game, they have to figure out how to stop the dragon, which fights Arthur and the Caballeros. Eventually, they discover that it can be destroyed by simply throwing the summoning page into Merlin's fire. Later, when Merlin beats the game and discovers that the "100,000 gold coins" he won are not real, he angrily throws the phone into the fire, which destroys a clerk at a cellphone store back in Duckburg.
