 * Before we see Gideon and Mabel close-up on the boat you can't see her headband.

The Inconveniencing

 * If the store was actually condemned, it is unlikely there would still be food there. Also, Dipper saw a newspaper that was dated back to 1995, meaning all the food would be expired and unsafe to eat.
 * If the store had been closed for years with the power off, then the ice they got from the freezer would have just been bags of water.
 * When the three teens reflections are shown in the window as normal, Tambry is smiling instead of just staring.
 * In the same scene, Tambry's leggings disappear.
 * Ma and Pa collapse from heart attacks by the window near the front door, but their bodies are chalked near the end of the store.S1e5_thompson_car_02.png

Dipper vs. Manliness

 * When Sheriff Blubs is eating pancakes, he is almost done, but when it shows the number of pancakes then back the Sheriff Blubbs, it starts from top again.
 * When Dipper is first seen walking down the street, the fire hydrant was fine and Sheriff Blubs and Deputy Durland weren't anywhere around it.
