Rowlet is a small, avian Pokémon resembling a young owl with a round body and short legs. Its plumage is primarily beige with a white underside and facial disc. The facial disc itself is in the shape of two overlapping circles. It has large black eyes and a stubby beak. The top part of its beak is white, while the lower half is an orange-brown. Its feet have two forward-facing toes and one backward facing toe; they are the same color as the lower half of its beak. Two leaves sprout from its chest, arranged to resemble a bowtie. Additional leaves form its tail and line the undersides of its wings.

This Pokémon is able to rotate its head almost 180 degrees, and has excellent night vision. Its feathers are as sharp as blades, which it launches at foes from the air.

Rowlet is based on an owl, sharing the most similarities with members of the Tytonidae family — species collectively known as "barn owls" that have heart-shaped faces and dark eyes. In particular, it closely resembles the common barn owl, which was introduced to Hawaii. Alternatively, it may be inspired by the Eastern grass-owl or African grass-owl, hence its Grass-typing.
Rowlet may be a combination of round or arrow and owlet.
Mokuroh may be a combination of 木 moku (wood) and 梟 fukurō (owl).
