Craft a hemoglobin cocktail from Ceratosaurus venom spines and blood packs, then feed it to a sturdy tamed creature with a strong saddle. Let the wild Ceratosaurus attack that creature without fighting back until it becomes fully intoxicated, then passively feed it extraordinary kibble, prime meat, or mutton while keeping it from getting trapped or interrupted. Alternatively, kill the adult guarding a baby and claim the offspring.
