Try to make this town happier by removing the piles of snow out of the way! This winter was long and it snowed a lot, that is why it became difficult for the cars to get out of the parking lot. Use your snowplow truck to push the piles of snow into the highlighted circles, where they will disappear and clear the way. You have to be fast if you want to get a higher score and you also have to be careful not to get stuck. Have a lot of fun!
