Tide Glider

The Tide Glider is a tidal class dragon introduced in Rise of Berk. They later became available in School of Dragons.

Description
This graceful Tidal class drifter doesn't "swim" through the water, it dances! Its saliva is said to have healing qualities... but it is too skittish for anyone to find out.

Trivia

 * The Tide Glider's healing saliva might have been inspired from Defiant One, when Hiccup told Snotlout Night Fury saliva did that, though he most likely made that up.
 * The Tide Glider is the first original dragon in Rise of Berk to appear in School of Dragons.
 * In School of Dragons, the Tide Glider sprays water. It is the third to do so, the others being the Scauldron and the Bewilderbeast. However, it is unknown if it changes the temperature of the water it fires like the others. Bubbles also form as the water is fired.
 * In Rise of Berk however, they shoot balls of acid.
 * According to this evidence, the Tide Glider can shoot both, water and acid.
 * Tide Gliders bear a strong resemblence to the weedy sea-dragon and the timberjack.
 * While the Tide Glider has hind legs in School of Dragons, it lacks them in Rise of Berk.
