Sweet Death

The Sweet Death is a Mystery Class dragon introduced in Dragons: Rise of Berk that later became available in School of Dragons.

Official Description
"This deceptive Mystery Class ambusher buries itself and uses its super sweet-scented tongue to lure its prey. If you have a sweet tooth, BEWARE! When the Sweet Death picks a sweet spot in a battle, it usually stays put until its acid attacks win the day."

- Dragons: Rise of Berk

Egg
These eggs are normally found yellow or orange in color. They appear to have sharp, straight edges. They appear to have an amber-colored liquid dripping down it, presumably the adult's acid.

Hatchling to Adult
The Sweet Death has a rather short and stubby body. It has a broad snout, wings, and a thick tail. The Sweet Death has a light sand brown color with stripe-like patterns that resembled a tiger's. The stripes give the dragon a somewhat bumpy and segmented appearance. In Dragons: Rise of Berk, the Sweet Death has a longer tail than in School of Dragons.

Titan Wing
Titan Wing Sweet Deaths are a pinkish-red in color, with a peach-colored belly. They still look rather stubby, with a thick tail. White spikes protrude from their entire body and their eyes are bigger. Also, their wings are light peach in color. A Sweet Death in titan form has a tail covered with smaller spikes.

Tree-like Tongue
Its tree-like tongue may be a camouflage. Unsuspecting victims may go closer to it to its tongue and it gives the Sweet Death an opportunity to strike. It appears to have pink saplings, according to Hiccup. As part of a mission, Hiccup mentions that the Sweet Death's tongue looks like a tree. Toothless seems aware of the danger and does not allow Hiccup to inspect the "tree" further. This shows that dragons may be able to tell that it is a Sweet Death and this camouflage is targeted at other animals.

Acid
Similar to the Changewing, the Sweet Death shoots highly corrosive acid at its opponents. It is great for achieving offensive and defensive goals, which makes it a dangerous dragon.

Tunneling
According to School of Dragons (Stable Quests) Sweet Deaths have the ability to tunnel.

Dragons: Rise of Berk
The Sweet Death, its Titan Wing form, and three individuals, the Seedling Sweet Death, the Exotic Sweet Death and the Masked Sweet Death became available in Rise of Berk.

School of Dragons
The Sweet Death also became available in School of Dragons, and the game also has a mask inspired by its design.
