Bearded dragon Pixel, orange-tan with blue chin dot

Yesterday around 3:30pm I slipped while cleaning Pixel's enclosure and he bolted out through the screen door into the courtyard behind my apartment on 6th Street in Sierra Vista. Pixel is about 9 inches long, orange-tan with a distinctive blue dot under his chin, and his tail tip is a bit frayed from a past snag. I last saw him near the entrance to the Sierra Vista Public Library on 3rd Street, where there is a small fountain and some potted cacti. He is a gentle, curious guy and really depends on heat lamps to stay warm, so I am worried about him in the cooler evenings. If anyone spots Pixel, please contact me here - I would be so grateful to get him back.
