School of Dragons
This is the fourth Toothless-exclusive Flight Club lesson the player can use. Instead of racing through hoops as other levels, the player must simply fly around the island on Toothless and find Hiccup and a flag hidden on the island (Hiccup is only named but not actually animated on the island).
