I am in the process of fleshing out an alternate world where, following an unnatural super-storm (think cold snaps down to -30°C and heavy snowfall in the 4ft range [1.2 m] inside of 8 hours) in the middle of June, a large number of people are cut-off in the Cold Zone. This zone reaches to the Northern end of Kansas, USA, while its origin point is centered over Hudson Bay in Canada.
The event takes place during high tourist season and as a result a lot of people unfamiliar with the cold northern winter climate will be present. The return of magic is occurring but is not immediately obvious. The unnatural winter is being caused by a magical tear leading to a hellish world of ice and snow. Due to the weakening of the fabric between our world and other worlds bordering it, various entities, structures, and monsters begin to appear in the Cold Zone. Especially during blizzards and other periods of extremely heavy snowfall.
I need a plausible way for this creature in particular to go largely unnoticed for 2-3 weeks.
Monster I Need Help Hiding
Snow Kraken: These great monstrosities are made up of snow and ice bound together into a semi-rigid shape anchored by runes lining its solid skull and the solid bases of its 10 tentacles which branch out from it. They are around the size of a school bus typically, but like an octopus can squeeze their body and compress themselves very easily. They hunt by feeling/hearing tremors through the ground as well as eyesight when peeking above-ground. They burrow through the frozen turf at roughly 15mph [24 km/h], but cannot burrow through solid stone and rarely go deeper than 40ft underground [12 m]. Fear fire and are usually encountered in dense forests and open plains. Although at least one has climbed up a mountainside so it could create avalanches and ride the waves of snow down. They can regrow tentacles if they lose one, but it requires them to have a source of ice and snow as well as 2-4 days.
Their rigid skull and tentacle bases are only the size of a smart car with ten golf club bag sized bases bristling off the back end around the creepily human-like mouth. It can contract its skeletal structure to roughly 1/4 the presented size here. So where could it hide in a modern world wracked by super blizzards where 4-6ft [1.2-1.8 m] of snow falls each day?
