While the concept is vaguely inspired by the interactive and augmented reality elements popularized by games like Pokemon Go, it does not use any assets, characters, or intellectual property from the Pokemon franchise. The interactions and conversations generated by this application are entirely fictional and created for entertainment and educational purposes. They should not be regarded as factual or accurate representations of animal behavior or communication. The author and the application do not hold any affiliation with the Pokemon brand or its creators, and no endorsement from them is implied.
