Snow machines look like big, rectangular machines with a large pipe protuding from the top. On the side of a snow machine are three lights and a crank.
Every once in a while, the crank on the side of a snow machine will start rotating and the lights will flash. Then snowballs will be shot out from the machine' s pipe, followed by arrows with indication marks appearing in various places on the level. These arrows indicate where the snowballs will land. When a snowball falls on the ground, it will create a block of ice where it was. Contact with the machine itself is not dangerous at all to the ice cream characters, but the falling snowballs are.
Snow machines can be considered the opposites of volcanoes, since they create ice blocks, and volcanoes melt them.
