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 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 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, the Bonsai Pokémon. Bonsly is the pre-evolved form of Sudowoodo. Although it looks like a Grass Pokémon, it is actually a Rock type. When it collects too much moisture, it produces fake tears to get rid of it.
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. Due to its weight, characters holding it can only move very slowly and it can't be thrown very far, but a direct hit does massive damage and can result in a knockout within two hits (at 0% damage).
"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."
Pokémon XD: Gale of Darkness: A Trainer at ONBS has lost their Bonsly. It appears at the S.S. Libra, but runs away upon being approached. Returning Bonsly to its Trainer gains the reward of the Bonsly Bingo Sheet. This begins with a Bonsly with Rock Slide, and allowed players to experience battling with it long before the official release of Diamond and Pearl.
Bonsly seems to be based on a bonsai tree (miniature trees grown inside small pots) and petrified wood (plants that have become fossilized over time). This would explain its pure Rock type since all of the organic material in petrified wood is replaced with minerals. It is also reminiscent of a toddler since its flowerpot resembles a diaper and it tends to cry a lot. It may also be based on the concept of mimicry.
Bonsly may be a combination of bonsai and sly or lie (referring to how it tricks others into thinking it's a plant).
Usohachi is a combination of 嘘 uso (false) and 鉢 hachi (flowerpot). It may be a play on 嘘っぱち usoppachi (downright lie).
