This Night Fury also has the painted war tail, vs just a wood tail for the flapping wings version. I believe the Hiccup kid figure, will fit to this figure, but I think I will pass, as he was kind of a dork. There is a larger Toothless with Hiccup set, that is truly awesome, but kind of spendy. It fires an electronic spinning energy dart, and probably does your taxes too.
Again, this Night Fury, has a slightly larger head to fit the energy dart. The dart is fully hidden when his mouth is closed. I like it without the dart though, so you can open and close his mouth, with leg squishing, to make it look like he's talking (not that he talks in the movie).
In short, if you want a Night Fury, this is an awesome opportunity. If you want something with more articulation, and posablitiy, build one out of bionicle legos.
That's the end of this tail
