Angel Statues

The angel statues are two Automatons that are at the Hoover Dam. They were made by Athena, and given to Zeus when it was built. The mortals think rubbing their toes will give them good luck.

The Titan's Curse
When Percy, Thalia, Grover and Zoë were being chased by Skeletons at Hoover Dam, they were trapped with the skeletons coming from all sides. Percy got Thalia to pray to her dad, Zeus, and the two angel statues started moving. The two statues carried them off to San Francisco, and then left.
