The Planet Express crew visits Amy Wong's parents, Leo and Inez, who are destroying the "old" Mars Las Vegas Strip and constructing a more extravagant one. A group of ecofeminism (calling themselves "eco-feministas") led by Frida Waterfall protest the destruction of the environment, leading to an accident that leaves Frida's necklace lodged inside Philip J. Fry's brain. The destruction upsets Leela (Futurama), but Leo has bribed Hubert J. Farnsworth to rubber stamp the project as environmentally friendly. Leela saves a Martian muck leech, the last of its species, from the site.
