A worm is typically long and skinny. But who says a worm has to only be a familiar “worm-like” length of long and skinny? Playing that thought out results in a ridiculous length of worm–maybe a tapeworm. But then the problem becomes what to do with it. Why not turn that weakness into a strength, and uniqueness, and have the suggestion of worm also create the very bird eating it. Rather existential, or cannibalistic? but more unexpected and, hopefully, more interesting.
