A mouse snuck into an ATM at a gas station in eastern Oregon and made what had to have been an adorable little home out of sixteen $20 bills. Nobody knows how Scrooge McMouse got into the ATM, but after giving the station attendant a good scare, he was fished out of his money pit and set free.

The mouse, discovered Thursday, had thoroughly torn up two bills and damaged another 14 to line his nest. Employee Millie Taylor says she screamed and slammed the machine’s door shut.

The bank replaced all the money that wasn’t extensively damaged, and the ATM has continued to work just fine.

The station will apparently not be renewing its limited-time special offer: free pet with every $320 withdrawal.
