Quetzal (pronounced "Ketzel") is a wise dragon who has been in Dragon Land for centuries. He is an expert on Dragon Land lore and is a great resource for Emmy and the others. He's the teacher at The School in the Sky, gently guiding the dragons and children on their voyage of self-discovery. His classroom is full of books, art supplies and surprises, including The Big Storybook - a fantastical almanac of sorts. Quetzal is the dragon the youngsters turn to when they need a grownup but the wise dragon never gives them a total solution. He just leads them to discover, on their own, the right path to take. In the episode "Just for Laughs", he is proven to be ticklish. He also has an identical twin brother named Fernando, who is rarely seen on the show.
Quetzal is a dandelion yellow dragon with brown spikes, has small wings, gray dots all over, some small teeth showing, and has a pendant of a dark green orb on a brown necklace. He has an old and wise look to him, adding to his character.
