Hiccup climbed onto toothless and saddled up, putting his feet into the peddles and moved his feet forward. Which opened the tail wing.
"Let's fly." Hiccup whispered.
The night fury, or toothless perhaps, galloped to the edge of the fjord and jumped, hiccup jerking his feet forward, the custom made tail wing flapping open, letting hiccup fly under the wide band of stars under him.
He flew over to the north mountain, following the sound of singing.
After after a few hours of flying he found a giant ice crystal castle that was shaped in a prism. Hiccup jerked the peddles forward and toothless went down, landing on a fresh pile of snow. He jumped off of toothless and patted his back.
"Stay back here, encase something happens."
