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. It is often mistaken for a Grass-type, but its body is biologically closer to stone.
Bonsly is a good mimic, making it often mistaken for a real bonsai tree, though it can easily stand out in a dry environment that lacks greenery. As its green spheres dry out, their dull luster increases. 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. As it cries, it expels both sweat and tears from its eyes; Bonsly sweat tastes a little salty, while the tears are slightly bitter. It dies if it gets too damp with this moisture. This habit also gets enemies to let their guards down. It prefers dry, rock-strewn 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.

Bonsly appears in Super Smash Bros. Brawl as a Poké Ball Pokémon. Once released, characters can pick it up and throw it at other players.

"A Bonsai Pokémon. It looks like a plant, but history reveals it is actually a Rock-type. Its best move among all its specialty moves is Fake Tears. As it grows, it will be skilled at using Mimic, which allows it to copy an opponent's previous move. If leveled up under certain conditions, it evolves into Sudowoodo."
