How to get a notification sound from iOS app?

Okay, so I have the Talking Ben app on both my iPad and my iPhone.
And every Saturday it gives me a funny notification, and makes a little Squeaky Toy sound. I want to take that sound and set it as my Txt Tone! Is there a way to open the App on my computer and 'Dissect' per se, to get a hold of the MP3/Sound File within the app that makes the sound?

I tried searching iTunes for Squeaky Toy sounds, but they really suck. And so do the ones on Google I've found.
The one from the Talking Ben app is perfect!

Any help? Any programs I can download to open internal files within apps?

You don't need a special App. The ability is right their on your Mac. Open your iTunes folder, then open your Mobile Applications folder, locate the App in question.

You will see it ends in.ipa, but really it's a archive. So the trick is, first make a copy as to not damage the original, then with the copied file change the last three letters to.zip, like from name.ipa to name.zip.

You will get a warning message, click Use.zip. The icon for the App should change to a zip icon.

Next you double click the App zip icon and it should unarchive to a folder. Delete the App zip icon, leaving you with a App folder. Note: Do not delete the orginal App.ipa file.

Open the App folder and open the payload folder, you most likely will see only one file in that, you need to right click that and select Show Package Contents.

From there you can try and locate the sounds or sound folder. Sounds most likely will be in.wav format.
