Corrected entry: The pink bear is missing his eye on different sides. For example in episode Seven Thirty-Seven he is missing his left eye, but in this episode he is missing his right. Both scenes are right at the beginning of the episodes. (00:01:10)
Corrected entry: In the opening teaser scene they show a man in a hazmat suit bagging evidence from the later revealed plane crash. One of the bags contain the eyeball from the pink bear. However in a future episode Hank discovers it in the pool filter, after the hazmat team would have bagged it. (00:00:55)
Correction: It's a reflection.
