A flying saucer filled with space aliens landed in my front yard! After the entire crew had filed out of their spaceship, I happened to count their heads and feet. I saw a total of 91 heads and 124 feet. It was clear that their leader was a purple creature with three heads and four feet. The rest of the space aliens each had two heads. The green ones had two feet and the blue ones had three feet.

How many of each type of creatures landed in my yard?
