Three Little Pumpkins Sitting Very Still

Three little pumpkins sitting very still, in a pumpkin patch high on a hill.
The first one said, "I'm very green but, I'll be orange by Halloween."
The second one said, "I'm on my way to becoming a jack-o-lantern some day."
The third one said, "Oh me, oh my! By then, I'll be a pumpkin pie!"
