Bonsly is a round, brown Pokémon with the top of its head resembling a club (♣). A rim goes around the middle of its body. There are three yellow spots on its face, two of which surround its eyes, which are small black dots. It has short legs and toeless feet. Bonsly also has a hole on its rear similar to the draining hole of a flowerpot.
Bonsly is a good mimic, making it often mistaken for a real bonsai tree, though can easily stand out in a dry environment that lacks greenery. It can remain in the same spot for a long time. It also has a habit of crying, not because it is sad or needing attention, but rather it is due to excess moisture in its body. It dies if it gets too damp with this moisture. This habit also gets enemies to let their guards down. It prefers dry areas, but it isn't uncommon to see one in a garden. As suggested by [[Brock's Bonsly]], a very young Bonsly needs to be bottle-fed but can eat solid food when it matures.
