Missable!During the first investigation In the Wizard City. There will be a red phone booth outside of Ron James store. When you first arrive at Wizard City the phone booth will be out of order. After gaining access to Ron James store for the first time the phone booth will be operational.
Now walk into the phone booth and use
to interact with it. You will randomly call someone in the Land of Ooo. After every call you make the phone booth will give back your money, repeat this process 10 times. This will be the only time you'll be able to do this.
There will be another point in another investigation where you will return to the phone booth and order a pizza. The option to call random numbers will not be available. So make sure to do this during the very first investigation.
