Dolphin

Dolphins encompass a wide range of aquatic mammals, all of which are social, intelligent, and widespread throughout the world's oceans.

Dolphins have a somewhat unusual trait—they often come to the aid of other creatures in distress, such as to save a drowning person or protect them from a shark attack. Not every monster in this book wants to hurt player characters— consider having a dolphin come to an endangered PC's rescue if the situation warrants it!
