No Seeds Allowed

While only a few scientists are allowed on the decidedly ‘new’ island, they’re also not allowed to bring in anything with seeds. One such scientist had gone number two at some point on the lava and a tomato plant sprouted from his, yup, his feces, leaving scientists originally perplexed until they figured it out. Since then, all scientists are thoroughly checked, in order to preserve the sanctity of the island since no one knows how long it will be around.
