The Tide Glider is a Tidal Class dragon released on January 16th, 2015. They can be purchased for 750 gems (600 for members) from the store.
From the How to Train Your Dragon Wiki:
- "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. The Tide Glider coasts along the waves peacefully, until it spots an enemy in the distance and shoots an acid ball to clear a path!"

- While they have hind legs in School of Dragons, they lack them in Rise of Berk.
