Corrected entry: While Entei is fighting Pikachu, he uses a number of fire attacks, yet the ice (which is completely surrounding him) doesn't melt at all. (01:06:10)
Corrected entry: While Entei is running off with Ash's mum on his back, he leaves ice "footprints" where he jumped right before entering an icy area. Yet these footprints are gone less that 5 seconds later, when Ash and Brock enter the same area. (00:37:50)
Corrected entry: When Ash, Misty, and Brock first head to the Crystal Tower, which is when they get Lisa's Poké Gear, they have no rope. When they get to the bottom of the waterfall, Ash suddenly has a rope on his shoulder. Where did it come from?
Corrected entry: When Ash & company climb up the waterfall, they need Bulbasaur and Chikorita to hold Ash like an anchor. Let's ignore the fact that they would probably slip due to the rushing water. In an earlier episode of the anime, Bulbasaur wasn't nearly as strong and was able to lift a falling Ash up a cliff from about twice the height without much effort. Why have both Chikorita and Bulbasaur out then?
Corrected entry: Just before Molly battles Misty, she finds out that you can be any age to battle, and returns to the form of a six year old, but her dress is sleeveless, but the real Molly up in the tower has little T-shirt length sleeves.
Corrected entry: When Brock is battling against the teenage Molly, he calls out Vulpix against her Teddiursa. However, all he uses are physical attacks against the bear. Since Vulpix is a Fire-type, why not use Flamethrower?
Corrected entry: In "Pikachu and Pichu", the short film before the actual movie, watch for the scene where the building that the Pokemon built starts to collapse, many Pokemon start rushing towards the screen and proceed to say their names. At this point, turn your volume up a bit and listen closely (and for the love of God, get the kids out of the room.). One particular Pokemon says his name (which is apparently something along the lines of "Smeargle"), followed shortly by the distinct words, "Shut the f*ck up", in the cute Pokemon voice. It sounds unbelievable, but if you listen to it, it's as clear as day.
