Wild Dragon Cliff (Books)

How to Train Your Dragon (series)
All of the Viking children in Gobber the Belch's Viking Initiation class have to travel to Wild Dragon Cliff to find a dragon for themselves in the dragon nursery. They do this by climbing into a cave filled with sleeping dragons and try to catch one, without waking all the other dragons or getting themselves killed. Unfortunately, Fishlegs, who is allergic to reptiles, sneezes and wakes up all the dragons. This is also wear the Monstrous Strangulator reaches up and kills dragons to feed its self in the under water cavern.
