Gosh, I don't know. All the pictures I pulled up for Roundworm look like they are the size of spaghetti and larger. Mine was a little tiny thin guy. Maybe it was an undernourished baby worm? (laughing)
Was yours as thick as cooked spaghetti or smaller? Mine was about 1/2 the size of uncooked spaghetti. And only one. Why only one? Makes me think this one was the dumbshi* who got caught by the P&B and maybe there are hundreds of others conspiring against me right now.
