Kowaina is a regular monster in Yes! Pretty Cure 5, serving the Nightmares. They are capable of possessing inanimate objects, and can also take objects from paintings to make them real. The name is a pun off of the Japanese adjective, "kowai na" (怖いな), which means "frightening". Unlike previous monsters, Kowaina is capable of growing its own limbs when possessing objects, instead of only taking advantage of the possessed item.
