The Hot Drink is a consumable item sold at the Snow Village (or at any Village once you unlock the Snow Village). It is the complete opposite to Really Cold Ice Cream as it will make you warmer instead of colder. The icon shows a small glass with some red/orange colored juice inside it. If you select it in your Pause Menu, like the Really Cold Ice Cream, it shall make the dog face on the side go back to normal (if you are in the snow terrain of course, not the desert!) and if you are in the desert, it will increse your heat.
