I have no idea whether or not this is real or Photoshop. Link (Thanks, Donnae!)

Pretty old in the Spanish side of the net… People still wonder if it was real or not. The story behind this was that someone found the frog in the “canónigos” (I don’t know the English name for this vegetable) bag he bought and was trying to sue the company Florette SA. This company is known for sometimes letting these amphibians make their ways into the salad bags, usually dead unlike this one.
If this is a fake then it’s not just a photoshopped image since there was a youtube video where you could see the frog breathing and moving inside the bag, that was unfortunately deleted by the user.
Proof: Spanish blog page that still links to the no-longer-available video, letting you see only a random frame before clicking the play button.
