Pendrils are penguins with drills instead of beaks who appear at Plank Beach; they battle Mario and Luigi by diving underground and then popping out of the ground before nose diving into one of the Mario Bros. Sometimes when they resurface, a rock will be stuck on their nose. If one of the Mario Bros. attack them with the rock stuck on them, the rock will shatter and a Bob-omb will run at the one who attacked. Eventually the Pendril will dive back into the ground and have the rock off them.
