Gentlemouse

Gentlemouse (Korean: 신사쥐, sinsajwi) is an Epic Pet that was released alongside its owner,, in the first half of the Lost Holiday update. It winds up toys that contains either a Yellow Bear Party or a Potion and then makes them move for points.

Story
''Among the many mysteries surrounding the Merrybear Toy Shop, it is said that all the toys return to the shelves on their own. However, that is actually the work of Gentlemouse, organizing all the toys strewn around the shop by young Cookies playing all day! It is said that Lollipop Cookie has been taken to the shelves once too, as the Pet mistook her for another of the shop's toys. Gentlemouse just shrugs off any compliments though, as exemplary behavior is al-mouse-t second nature to this companion!''

Trivia

 * Gentlemouse's internal name is "pet0210".
