An algae bloom can cause your doom / If you eat the shellfish / It will be your just desserts / If you’re very selfish
An algae bloom can make you ill / Please don’t eat the oysters / If you do, like aging nuns [you] could be in 6-feet under cloyster
An algae bloom could cause distress / if you eat some mussels / Which will affect you inside-out, especially [the] corpuscles.
