Muka

Muka is a monster cactus living in the desert. Although it's usually quite passive in the presence of travellers, it gets furious and shoots needles or cactus water toward enemies when attacked. Cute cactus commonly found in the desert. It tries to threaten passersby with its shrieks, but its noises are too funny to be scary.
