User blog:The Woolly Howl/Unknown Dragons from RTTE Map

Hey guys! I've just looked through the Hicup's online Race to the Edge Map and noticed some unknown, new dragons. Can  anyone help identify it?

Dragon 1: Uh... Sorry, not idea! Looks kinda like a

Thunderdrum, but the face and the tail is different and it appears to have only two legs only and they are front legs.

Dragon 2: Looks like a combination of a Scuttleclaw, Thunderdum and other dragons -_-

Dragon 3: Also known as the Walt Ostx from the unknown dragon page. Looks like a gronckle as it has really bumpy skin and is rather hefty. However, it has larger wings, a more  'retangular' body and two strange horns on its head. Boulder class, perhaps? So... What do you guys think about them?
