If you want Hiccup to get the hiccups, Tuffnut to do the chicken dance, or ANY HTTYD character to do ANYTHING, you're in luck. I'll write you a one-shot of it! Just comment on a chapter with your truths or dares for characters.
While you're at it, you should probably read everyone else's dare stories. They're random and funny.
*Disclaimer: I don't own any characters listed herein, other than The Author*
*P.S.: Heather is evil. You cannot dare her to be good.*
THAT IS ALL. Now go read something.
