Dr O Soozana and the Eco-X

Plastic. That manmade stuff which won't go away. You can't burn it, all you get is a big lump. Burying won't make it disintegrate like natural substances etc. It just piles up into a big mess. Dr O spends twenty years creating a creature whose only sustenance is the petro carbons that is the main ingredient of the stuff. He is wildly successful creating a world wide demand. He partners with a company that insists on increased production to meet the demand.
Only adding reproduction would apeed up the process. Dr O has a healthy respect for the laws of nature and he is afraid of the results which is a mystery. O decides to take the plunge. Bad move. Chaos is a resultt of his decision leading to hilarious results.
