Crabs
There are species of crabs that house themselves in discarded shells. We’ve seen some varieties in the pet stores. Others still, will spend time camouflaging themselves with debris from their native habitat. Those are the ones that stick in my mind. Their “fortress” renders them invisible to predators, but can become an unweildy mass. I think this happens to people. We try things on and continue to try new things until eventually we can’t see ourselves under the costumes.
