Do you get the monologue from mother squirrel after digging it out?
Yeah it's the spot by the signpost at the edge of the woods.
Not really it just digs like a normal snow mount
Then it's probably the wrong spot. It's 2 tiles directly south from the signpost. Before that, you need to talk to Fabian so you know there's a hidden stash. It's only available in winter.
We can talk on discord (zionwarez) or X, if you like.
