Here, predators pursue their prey like normally, but not for the purpose of killing and eating their prey, rather to tickle them, as laughter is food. Predators here have certain adaptations to keep them from hurting their prey. Prey also have certain changes that allow the predators to catch them more easily. While being hunted, they still react with fear and try to escape, but that fear will fade while they're being tickled. After the predator finishes tickling the prey, the prey is released.
