With triple-split jaws on each of this Mystery Class Dragon’s 4 heads, it looks like a Venus Flytrap, just not as friendly.
The Snaptrapper is a dragon that has four heads, each with three jaws. Their tails are forked like the Hideous Zippleback's, and they look somewhat like the latter as well. Their unique, frightening jaws open up in a way that resembles a flower blooming, and the spines on their neck, body and tail look similar to leaves. All four heads of the Snaptrapper have three tongues; these tongues each resemble the anther of a flower, as it is the Snaptrapper's tactic to resemble a plant of some kind to lure prey in close, or to help them hide from the dragon's few potential predators. They are one of the larger species of dragons, and have very long necks and tails.
While as beautiful and serene as an exotic flower upon first blush, the four-headed Snaptrapper is actually one of the most insidious and deadly dragons ever discovered. They will lay in wait for days in hiding hoping to lure unsuspecting prey to their jaws.
The Snaptrapper is known to breathe a flammable mist containing methane, and can produce the smell of chocolate from their mouths to lure in potential prey. They also spit acid that can sting foes and even melt through metal. Superbly stealthy hunters, they can excellently camouflage themselves amidst dense vegetation, both to hide from larger dragons and from their prey. As shown in the Book of Dragons short, these dragons are capable of swallowing a Viking whole.
The Snaptrapper also has the most deadly venom of all dragons.
It can also release a horrid odor that can scare off even the most starving Titan Wings.
Snaptrappers are not the most nimble flyers, a drawback of their heavy adaption for stealth-based hunting. However, their long, thin necks and tails are very flexible, similar to those of the Hideous Zippleback.
They are incredibly patient. They will wait for days, motionless, waiting for food.
How To Train Your Dragon (film)
The Snaptrapper first appeared in the film within the pages of the Dragon Manual when Hiccup was trying to find information on Night Furies. He did not state the dragon's name, although the book read that Snaptrappers are extremely dangerous, and should be killed on sight.
Book of Dragons
They are categorized in the Fear Class like the Hideous Zippleback. They attract prey with a sweet smell of chocolate, which emanates from all four mouths. Like all dragons, they shed their scales and talons, but these eventually regrow. Snaptrappers love rain and enjoy splashing in the mud, which could be based off the fact plants need water and damp areas.
In this comic, Gobber tells about when he and Stoick fought a bunch of Snaptrappers.

Titan winged Snaptrappers have four heads and triple-spilt jaws with more teeth. They have developed a small tuft of pink petal-like structures at the back of their head. They have dark brown wings with some blue spots and yellow network vein like patterns, as such, their wings resemble dead leaves. Also, their neck is clearly segmented and has spines protruding from the back of their necks, all the way down to their tail, which eventually splits into two yellow tails.
- The Snaptrapper is based off a Venus Flytrap, and also resembles both the Hydra from Greek Mythology and, to a much lesser extent, an European dragon.
- In the Book of Dragons Short, the Snaptrapper is said to use the smell of chocolate to lure its prey; however, chocolate was unknown in Viking times, due to it being native to the Americans. It would have been more realistic to use honey, which was known to Vikings and more likely, since it is made from the nectar of flowers which the Snaptrapper's heads resemble. This might be a shoutout to the books though, due to one of the villains trying to find America.
- In Dragon Tracker Part 4, the Snaptrapper was mislabeled as the Snappertrapper.
- The Snaptrapper is one of the five dragon species that doesn't have forked tongues. The others are the Flightmare, the Snow Wraith, the Razorwhip and the Woolly Howl.
