Trickster soon tilted her head to the side at the sound of something whistling. Thankfully, it wasn't at a dog whistles pitch, so her ears twitched and she was fine. "A new sound!" She happily stated, mimicking the voice of a woman who was roughly in her twenties. She seemed to smile as she rushed towards the source, hoping that whatever or whoever made the sound would be able to change to a different one. "This is exciting!" She said once again, but in a quieter tone, hoping not to disrupt the new sound from being played.
