Wandering Around The North Pole

Upon entering the north pole, as a first step, we talk to Santa who states his 5 golden rings have gone missing and seeks help.
Upon talking to Santa, several objectives get unlocked.

We are tasked with recovering the 5 golden rings

In the north pole, we meet with Chimney Scissorsticks.

Chimney Scissorsticks notes that there are elves burrowed under the snow.	There are three tunnels in the area but looks like there is only one of them we can get into.	Upon entering, we can see there is a ladder which lets us get down the tunnel.

Went down the tunnel and looked inside each tunnel door. Each tunnel door (except hall of talks) door is named after a golden ring and has objectives/challenges to solve which implies if we solve all the objective behind a door, we recover the corresponding ring. In addition, we get Kringle Coins (KC) upon solving objectives which may be used to buy hats and NFTs.
