Under this layer of vegetation, a shade-loving snail has been invaded by worms. These parasites take over the snail's brain and push into his tentacles, transforming them into swollen, colourful, pulsating targets. At dawn, the snail leaves the protection of the vegetation, climbing toward danger. Out in the open, in the hot and dry sun, the snail is exposed and vulnerable. The pulsating tentacles mimick a maggot, the perfect meal for the parasites next host: a bird. The snail will likely survive this attack, but more parasites are growing inside its body and will move into its regenerated tentacles. The worms are ingested by the bird and will begin to reproduce. The bird spreads thousands of parasite eggs throughout the forest to infect more snails.
