An anomaly from the SCP Foundation. It appears on the play store every now and then. You can't open or uninstall the app, as there's no icon that appears on your phone. After a few hours, you get a text from an unknown number. It shows a picture of a strange creature that has an animal skull for a head, and it's covered in black hair/fur. It's hands and feet are skeletal. Every few hours, more photos are sent coming closer and closer to your location, while being at places you frequent.
