Isle of Berk/Dreadfall
Berk's Dreadfall Variant goes from an orange hued sky with a sunrise to a cloudy, full moon, gray-ish black night, the location itself has mixtures of purple and orange hues, filled with jack-o-lanterns lighting the entire place and some spider webs between sea stacks and enclosed spaces.
The center features two tall brazier with a green hue and every entrance to the houses contain about 4 jack-o-lanterns lighting the way.
Between Ruffnut & Tuffnut's house and the Blacksmith, there's a withered tree with little skulls hanging from them, which is an item you can buy from the Store for your farm, there's also multiple spider webs between the houses.
However, when the player goes to the upper section, the entire Great Hall's stairs is filled with jack-o-lanterns and webs are around the statues and Hiccup's house, there's even a large, fake spider hanging from Hiccup's house's dragon head.
The floor has a bioluminescent painting of a dragon head and behind Hiccup's house, a swarm of bats constantly come out of the rocks. There's also another withered-esque tree right beside Cloudjumper, also with a dragon head painting.
The biggest attraction that opens during Dreadfall is Loki's Maze (now named Fright of Passage) which every year has the exact same minigames, just with different placement and very slightly modified but, often times, the reward the player gets from them can be... intriguing. Well, for the most part.
