User blog comment:Astrid Skylar/Who thinks that they should make a third one?/@comment-25102735-20140625045205

Apparently, they're thinking about making a fourth movie as well! I'm not entirely sure if it's official or not, but it would be amazing if it was! Only if it were necessary, of course XD

But I think it might be, since HTTYD 2 left us with A LOT of possibilities on what could happen next.
