Simon Sea Monkeys

Simon Sea Monkeys are killer shrimp that people make by putting geniticly modified rice in tanks.

Creation
They were made to teach kids how to look after pets but than they turned evil because a guy named Simon mutated them and they evolved. First they were harmless and then they grew a bit and behaved like pirranahs. Then they grew the size of cats and people had to buy pools to keep them in. Then in the summer people went swimming in the pools and were attacked by the SSMs. Then they evolved to the size of tigers and went on land and attacked even more people. Than the plants had to stop them. The plants killed them all though
