Synopsis for "All Flesh Is Grass!"
Chris Larmouth, who has been hired by Warren to serve as the team's aviary mechanic, is drinking a protein shake made with alfalfa sprouts he grew himself. After he drinks it, his body starts to mutate and plant-like tendrils emerge from his body. Beast and Iceman see this over their security monitor and race to the rescue. They recognize the plant creature emerging from Larmouth’s body as the same one they had previously fought that grew from Ephraim Soles.  Iceman freezes Larmouth, and they take him to their bio-lab.
Meanwhile, in the New Mexico valley, a family witnesses a stampede of horses that are being ridden by plant-men who appear to be growing out of the horses. Beast, Iceman, and Gargoyle have to get past more tendrils to get Larmouth to the bio-lab. Beast tells the other two to seal up their headquarters so nothing can get in or out and to call the other Defenders. Outside the window, Iceman and Gargoyle see monstrous rabbits with fangs that are all connected by tendrils. We flash briefly to Angel's plane as the heroes returning from Ohio check in with the trio at the homestead via Moondragon's psi-talents.
In the bio-lab, Beast examines the plant creature through various scientific equipment and discovers the cells contain a radioactive organelle, which causes them to rapidly reproduce and mutate. As the other Defenders arrive, Angel discovers a green fog and almost flies into it until Moondragon mentally warns him away, and he sees an owl fly into the fog before emerging from the cloud covered in spores. Soon, the entire valley is overrun by mutant plant creatures, which merge together into a giant, slug-like form that anchors itself to Defenders' Mansion in order to send out spores.
Realizing that the spores would spread around the world, Moondragon enters the creature and is able to detect the energy pattern of its mind. She realizes how it may be destroyed but lacks the power to do so. Moondragon then mentally contacts the Gargoyle, who also enters the creature, and links her mind with his so that he can understand the cellular structure of the slime mold. With this newfound understanding, Gargoyle is able to target the weak point of each cell with his bio-mystical blasts, but unfortunately, the radioactive myxomycete begins to secrete acid onto the two heroes. Moondragon asks the other Defenders to attack the creature and keep it occupied, while she becomes one with Gargoyle by kissing him. Gargoyle’s severed hand suddenly regenerates, and his power, combined with Moondragon’s, destroys the creature and dissolves its remains.
