#objectively the patterns made him fit more into the artstyle of the universe + make him seem like a real animal

Now that I think about it, that one 'Toothless lost his patterns because they were his baby features' argument is just stupid and wrong. Their kids (these ugly ahh dragons made to resemble kittens/puppies) don't have any patterns either (not clearly shown in the picture because I couldn't find a clear one with all of them).

By that logic the kids should definitely have patterns because 1: the father had them (movie 1 and 2 but less prominent) and 2: the mother still does. They're still babies so if the patterns were indeed a 'baby' feature they should have them as well, especially now that they're young.

My point is, removing the patterns from Toothless was a 'stylistic' decision despite whatever people think. Or, if it were intentional, they completely forgot about the whole thing (in the same movie they removed them, which makes zero sense)

Also their heads are different from httyd 1 Toothless too, which again shows that they just wanted to change the structure of the model.
