Bullrougher

A Bullrougher is about the size of Gronckle. It has one very sharp two foot horn on its forehead. They use their horn to charge at their victim. Bullroughers live in grassy, mountainous lairs in large caves. They can shoot long flares of fire and fly with their large wings. One, named Goliath, was killed by a Exterminator in How to Twist a Dragon's Tale, and Gobber the Belch owned the Bullrougher called Goliath.

A Bullrougher named Grump will be Gobber's dragon in How to Train Your Dragon 2.
