Thing 26

The orange creature, also called Thing #26 is a short, round monster that Dipper and Mabel Pines encounter in and try to get out of their closet during the original trailer. In Dipper's postcard to his parents, he includes a picture of the beast and asks them to send help and/or weapons. It is shown once again as an enemy in Fright Night. He has big, red eyes and fangs.
