I LOVE THIS MOVIE SO MUCH but when i rewatch the movie in the introduction of the twins there dragon barf and belch were the wrong heads because in the movie barf is in the right side while belch is the left side in the other movies and tv shows barf is the left side while belch is on the right side and belch lights the gas and barf releases the gas but in the movie barf lit the gas and belch spray the gas BUT I STILL LOVE THE MOVIE if DreamWorks is looking at this pls fix this it with the DVD version
