Horrorcow

Horrorcow is the name of the female Basic Brown dragon owned by Fishlegs.

Horrorcow is captured by Hiccup who gives her to Fishlegs because he cannot catch a dragon himself.The horror bit is to add some scaryness to her name,while the cow bit reffers to the fact that she is not remotely dangerous and spends many of her time in deep sleep.Fishlegs suspects she is vegetarian.She is the same size as Toothless and is his best Dragon friend.
