An employee at the Gem Stop Chevron in La Grande got the surprise of her life when she opened up the automatic teller machine and found a mouse inside a nest lined with $20 bills.

The ATM continued to work just fine, despite the mouse discovered on Thursday.

The mouse had chewed up two bills and damaged another 14 to make his nest, but the bank replaced all the money that wasn't extensively damaged.

The mouse also got a reprieve: He was evicted from his nest but set free outside.

The store's employees are still mystified about how the mouse got inside the ATM.
