Is the glitch Pokemon "Female sign"'s cry actually endless?

Question

I heard that its cry is possibly endless. I, however, am not so sure. I need a second opinion.

Answer 1

♀ . doesn't have an endless cry, but it can occasionally cause endless unrelated noises that will freeze the game.

[The glitch Pokemon] can also replace the battle music with never-ending glitchy sounds that don't allow its cry (which is identical to Raticate's) to play, effectively locking up the game.

Answer 2

It is possibly endless and it could be in a loop here is the source http://bulbapedia.bulbagarden.net/wiki/♀_.
