Here is a another GIF image of Toothless playing but in this one he is playing with Hiccup. I turned this scene into a GIF. It's from How To Train Your Dragon 2. The movie and this clip turned into a GIF is owned by Dreamworks, an amazing company.
This one is similiar to the image located here: www.deviantart.com/art/Death-B…
I just cut mine and made it a little shorter.
I just did the same scene as a GIF. I did not copy this one because the saved image doesn't work and animate when I saved it. I had to re-animate it in Photoshop.
Hope you enjoy this one too.
