Tangled Heather x Fishlegs

{Just replace the characters in Tangled with the ones in Httyd and Rtte}

All her life, Heather wanted to see those mysterious lights that glowed every night on her birthday. But her mother never even let her leave her tower. So, when a runaway thief scaled her tower one day, the first person she ever met, she decides to make use of him. At the same time, her mother left for a 3 day journey, so that's plenty of time for her to go see the lights and return.
Right?

Same plot, just slight differences between the scenes.
- Like when Flynn and the twins escape the castle, Fishlegs, Hiccup, and Snotlout escape the castle on dragons, across the forest.
- And when Max chases down Flynn = Fishlegs vs Stormfly.
- Heather has black hair, Rapunzel has blonde hair.
