- I would assume that using Mystery Gift just activates other Pokemon in the cave, like having a GBA game in the second slot just magically activates the DS mode. It isn't mentioned in the Mystery Gift article though..... — THE TROM — 07:44, 11 February 2009 (UTC)
If that's the case, why the heck did they put it in English games?! User:?????
- Best guess: Nobody at the time knew there wouldn't be a way to shift the Altering Cave Pokémon in international releases, event or otherwise. Besides, it's a good way to raise stat experience in Speed even in an unshiftable state...--Shiningpikablu252 00:06, 24 December 2009 (UTC)
- There was no event for Altering Cave anywhere. This is not the same as Crystal's GS Ball or Emerald's Old Sea Map, which were distributed exclusively to Japanese players; no one has ever utilized the cave by legitimate means. --Unown Lord 09:23, 2 January 2010 (UTC)
I've heard that the additional Pokemon could be unlocked in japanese games using the eReader and in the international releases this was switched to "regular" mystery gift... Can anyone verify this? TCCPhreak 18:09, 10 July 2011 (UTC)
I used to own the Prima Games guide for FireRed and LeafGreen, and in the Pokédex section, I'm pretty sure it gave some of these Pokémon the catchable location "Cave of Origin" which I always assumed was an error referring to Altering Cave. Does this sound plausible? It wouldn't be the only error: it also referred to Sabrina's Alakazam as "dead" after you defeat it, and I also remember it saying Miltank could be caught at "Cave of Origin."

- Yes, this is noted on the Cave of Origin page. I've also added it to the Pokémon FireRed and LeafGreen: Prima's Official Strategy Guide page now. --SnorlaxMonster 04:21, 13 July 2017 (UTC)
