Remlit

Remlits are an animal species found in Skyloft in Skyward Sword.

Characteristics
They are well-mannered in the day, but they exhibit aggressive behavior at night, prowling in the dark along with other evil creatures. These Remlits will not hesitate to attack Link by leaping at him, but will cower after being struck a few times. After Link turns Batreaux into a human, the Remlits stop being aggressive and monsters no longer walk at night.

Mia is a beige Remlit belonging to Zelda and Gaepora that has a habit of scampering off. Link can help Horwell find Mia at the beginning of the game. During the night when Link chases Fi, he sees Mia again, but to his surprise, even she has become aggressive.

Trivia

 * Link can throw Remlits off the edge of Skyloft in either of their forms.
 * Remlits have the ability to fly in both forms, as they can flap their floppy ears to gain altitude.
 * Remlits are one of the few enemies that can't be killed.
 * Horwell keeps a scratching post set in his room for Mia to play with while he is watching her.
