Mr. Sandoval

Mr. Sandoval is a resident of Greg's neighborhood who only appeared in Hard Luck. When it was snowing, he put two poles to mark the pavement so that the man who plows it know where it is. One day, Greg and Rowley plucked out the poles and started playing with them and later put them about 10 feet away from where they originally were. This made Mr. Sandoval angry and according to Greg, till now he is waiting for them to show their faces, because of that Greg would cover his face whenever passing by his house.
