Harsh weather has reached Berk, colder than ever seen before. Due to this, Trader Johann has not arrived at Berk, so Hiccup insists that he go look for Johann. Out at sea, he finds that everything has frozen over, explaining why Johann hasn't arrived yet. He finds Johann and travels back to Berk with him. Back at Berk, all Vikings have mysteriously disappeared except Fishlegs, who explains to Hiccup that Speed Stingers, a venomous non-flying group of dragons, have travelled across the frozen sea and attacked Berk, causing the Vikings to evacuate.
This is a fun, unique episode. The Speed Stingers are interesting and the resolution to the episode is satisfying. Nothing so far has caused the Vikings to evacuate Berk, as they usually hold their ground. I think what makes the episode enjoyable is it being a fun little adventure that is completely unique. But there's nothing to it past that, bar the new Speed Stingers. I think a seven fits this episode best.
