"Leah was as pretty as a princess."
"These unusual owls had brightly shining blue and red feathers which were as beautiful as sapphires and rubies."
"The dog seemed as smart as a human."
"Raven who was the toughest, meanest girl in all Ventura, teased her hair so high it looked as big as a beehive.
"He was as angry as a gorilla."
And my all time favorite (for this year):
"She was as worried as a porcupine carrying a bundle of balloons."
