When everyone first arrives back in the real world, Porygon is seemingly floating in mid-air above Misty's head; however, one cut later, it is between Misty and Brock. See more »


Satoshi: [about the transfer machine error] Joy-san, just what is happening here?
Joi: What hasn't been happening? I want to know too, for example, when we transfer a Pokemon as rare as say, Kyukon, The Pokemon that arrives is switched, and the original never gets there at all! Anyway, it looks like a bug in the system is causing it.

Mental trip
10 March 2008 | by The_Bastard_SonSee all my reviews

Before going on I'll have to ask myself if those guys that reviewed this before me have a clue on what they are talking about. It seems no one have actually seen the episode. And by the way, no one, luckily, died after seeing this. The ban of this episode is not because of the story itself, but because of 105 blue/red flashing lights in 5 seconds (yeah, you've read right!). The synopsis is not big deal. I mean, it could be good for a 10 years old boy, but for other is not great. Not terrible, but not great. 4Kids dubbed it, and slowed down/applied filther/did everything possible to prevent seizures, but probably since this episode gave Pokémon such a bad reputation, they decided to never show it. Well, after all it's an episode like another on the Pokémon series, not great, not terrible. If it wasn't for seizures, this episode wouldn't have been remembered
