Bells of Frey

The Bells of Frey are a mythical object that appears in Dragons: Rise of Berk.

History
After finding the Green Death near Berk, Hiccup decides to search for other Legendary dragons. Gothi then shows the riders one of the Bells of Frey and tells them a legend: "The Bells of Frey will wake the sleeping giant. For it stays hidden if too silent. Over trees, and under seas. To wake this dragon ring all three." She also tells them there are three bells and the r iders quickly began nto search for the other two. Shortly after, Hiccup finds the second bell in the forest. However, no one is able to find the last bell.

Thinking they might cause trouble, Hiccup tells the twins to the fish and wood they collected on Berk. However, they burn it, making a horrible smell. On the bottom of the Fish Basin, the twins find the third bell, unknowing what it is. Hiccup then recognizes it and puts it with the other two. All the riders then fly above Berk and ring all three Bells of Frey. Soon, a Foreverwing awakens from underneath the boulders where it was sleeping.
