I agree with Rich196 about it being a senko and they do expand and don't breakdown in a fishes stomach. It's quite disturbing at the number of soft plastics that one can see lying on the bottom of lakes with good water clarity. In recent years I see more and more 15" to 17" bass that have a normal size head but are very thin, they generally give a good fight but definitely have a problem and I figure that it's most likely soft plastics in their stomach, not much room in their stomach for much else. Please take your old soft plastics and put them in the garbage, not into the waters you fish. Senkos seem to be the biggest culprit. IMHO
PS: This is a picture of one that was very thin but this isn't a good angle.
