Where can I find the File responsible for the Android Version Easter Egg

Hello I was wondering where can i find the file responsible for the Android Version easter egg where you click the android version on settings 3 times. Can anyone tell me what is the name of the file or apk and where can i find it? I'm using Galaxy Note 1 (SHV-E160S) with a custom touchwiz 4.1.2 rom. Thanks
