MUTANT BUTTERFLIES!

After a nuclear disaster, scientists discovered something that sounds like it came out of a science fiction book... MUTANT BUTTERFLIES! Big mutant butterflies. Now that sound creepy. I guess the nuclear disaster made butterflies change into mutant ones. It sounds fake. But it is real. Mutant butterflies? The next thing you know, there will be flying pigs! I personally never really liked big butterflies. But seriously, MUTANT BUTTERFLIES? That is crazy! Does this mean nuclear diasters can change other animals, or maybe even humans? We better be careful or we might end up becoming mutant human living with other mutant animals. I hope I don't find any mutant butterflies in my path one day.
