An organism who habitates in city ecosystems. This animal is adorable. Some features relating to a monkey. At times, when it is humid it may let out an incensing odor. But it is harmless, but may hurt your nose. It is rather tall and friendly. When a kleant is young it may be a bit chubby, and small. But as it gets taller it stretches and becomes tall and skinny. It also makes unusual sound effects, when bothered.
