How do you get the gold mouse in the kcichtien in luigis mansion?

To get the gold mouse in the Kitchen of Luigi's Mansion, you need to wait for it to appear. It spawns randomly when you walk around the area, so it's best to move around and interact with objects to entice it out. Once it appears, quickly use your Poltergust to vacuum it up before it escapes. Make sure to be patient, as it may take several attempts for the gold mouse to show up.
