New New York creatures

The New New York creatures are mutant monsters accidentally created by Bart.

History
When Bart threw a Sandwich with his boogers in a time capsule, the microbes in the Sandwich reactioned with Milhouse's lucky rabbit foot and that created a mutant-rabbit creature. That creature multiplied itself and millions of them were created and started to destroy New New York, the 31st century's New York.

They then started to evolve to an aspect of green Bart-look-alike creatures that did the same jokes Bart did 1000 years before. After this; Lisa, Bart and the had an idea to get rid of them for ever. They trapped all the creatures in Madison Cube Garden and threw it away to the space.

The Cube then landed in Omicron Persei 8 where Lrrr started eating them because they were delicious for him.
