Green Giant by Jack Prelutsky (I find this very cheery)

There lived a green great giant whose name was Sam
His hair was the color of strawberry jam
He had one brown and one blue eye
And a beard the color of pumpkin pie.
His coat and pants were oh so bright
Like a peppermint stick all red and white
His socks were as brown as a chocolate drop
His head was the color of gingerbread
With a tall, tall feather of raspberry red.
