Yo, I'm Grimy McTrollkins.
I'm a troll and I work for the big guy over there: Jack Frost.
I’d rather not be bothered talking with you, but I’m kind of in a bind and need your help.
Jack Frost is so obsessed with icy cold that he accidentally froze shut the door to Frost Tower!
I wonder if you can help me get back in.
I think we can melt the door open if we can just get access to the thermostat inside the building.
That thermostat uses Wi-Fi. And I’ll bet you picked up a Wi-Fi adapter for your badge when you got to the North Pole.
Click on your badge and go to the Items tab. There, you should see your Wi-Fi Dongle and a button to “Open Wi-Fi CLI.” That’ll give you
command-line interface access to your badge’s wireless capabilities.

Following the documentation, we make use of /cooler endpoint passing a temperature which may melt ice e.g., 110 degrees 

curl -XPOST -H 'Content-Type: application/json' \
  --data-binary '{"temperature": 110}' \
