Found something disgusting inside

I found something's inside the pasta sauce and not sure what it is, it has a black piece that opens up and it's hard on the touch. 1 has just the black piece, the other one has a soft slimy piece stuck to it. The closest thing I can think of is some type of mushroom but I have never come across a mushroom that looks like that, but the thing is there is no mushrooms in the ingredients list. Looks more like some creature and just feels gross. I only found this after eating half of bottle when I retrieved back from the fridge.
