Roger has the power to attract and tame virtually any animal. This is sometimes played for laughs, such as when was attacked by ants in "Amazon Adventure," or seriously when he has to take care of the valuable animals in ‘’AmazonAdventure’’. The most prominent examples of his ability is when he tames a furious man-eating lion in "Lion Adventure" with a few softly-spoken words. He has also tamed crocodiles, infant gorillas, polar bears and a killer whale and an elephant, to name a few, during the course of their adventures.
