Ability to make burrows in heavy snow for cold resistance

Just started thinking about some things animals in real life do and thought it'd be nice if nichelings could dig small holes in the snow to get some cold resistance. It shouldn't be extremely easy to make, should take like 3 digging actions to make a big enough hole for one nicheling.

Aww! That would be super cute! I am imaging a mother with her baby, cuddling in the hole, watching the snow fall down. Amazing idea!

digging paw or digging snout could reduce the time needed. Bonus points if you could dig in through multiple snow piles to make networks of tunnels that travel about, revealing things such as berry bushes and other resources to allow you to collect from them still.

Maybe some predators can't get you either!

Perhaps you could also be able to burrow in the savannah to give your nichelings some heat resistance due to the shelter the hole would provide from the sun.

I'm picturing two blinking eyes in a hole, or eyes blinking in a hole under an upside-down nest. Possibly two big eyes and up to four little eyes if babies fit. Maybe dig 3 time but still need 2 actions, 1 action to build the nest and 1 action to enter the burrow.

I like the burrows as a shelter from weather but digging could also be a way to stop fire because grass wouldn't grow there or it would take longer to grow on dug tiles. Also they could put fires out by kicking sand / dirt on the fire on neighboring tiles.

This is similar to a Digging post but that one also talked about digging tunnels. Tunnels could be added but not sure how it would work.
