Why does nyan cat say oh hey Hannah?

Hannah is the dog who nyan often passes in the game, that means she is near by or has passed.

No, on Nyan's page he had a status saying he needed new speech bubbles, and my friend was commenting on it, and I said oh hi, and she said, Oh hey hannah, and nyan said oh hey hannah speech bubbles? Special edition? and then that has been there ever since and eek <33
