Azumarill is partially based on a rabbit. As with most other Pokemon, its design draws from multiple sources of inspiration.
Azumarill may be based on a combination of a rabbit and a beach ball or possibly a personal flotation device or lifebuoy. It could be also possibly based on the swamp rabbits, which have a strong preference for wet areas (such as cypress swamps, marshes, floodplains, and river tributaries) and that will take to the water and swim. Azumarill's water-like splash pattern may reflect from the camouflage of countershading of aquatic animals such as sharks and penguins, being that they have a dark coloration on top to match the dark water underneath and a white coloration on their under to match the sunlight from above. Its body shape, rabbit appearance and body pattern could be a reference to Easter Bunny and Easter eggs. Azumarill's resemblance to a rabbit likely influences its Fairy-type and its ability Huge Power (which serves as a pun for "fortifying mochi"). These aspects may draw inspiration from the moon rabbit legend, where people interpret the dark markings on the Moon as a rabbit. The choice of the Fairy type is also fitting, as it is often associated with the moon and sweet treats.
