Just found your comment about that article stub. I can help in the range I can do, yet, there are so many affiliated topic, such as the games, are those I have completely no ideas yet, but once I reach them, maybe I can help.
Don't know if this can make you feel better, but this is what just came up to my mind.
Could you please replace these images S1E11 Our winner is Stan Pines.png, S1E14 Shoppers in the gift shop.png, S1E14 Soos attacks Dipper with a broom.png, S1E15 Mabel falls on to the balls.png, S2E8 The Gang getting ready.png, and S2E8 The gang is going.png? Cause I realized that these images have some black lines at the bottom two.
