3rd Gen Tera Cave Question (Emerald)

[Mr. Slowpoke]

So I'm playing Emerald for the first time and I'm in the Tera Cave to catch Groudon. I feel like my Pokémon aren't at a high enough level but when I leave the cave it disappears. Does it reappear at all or am I pretty much pooched if I leave and don't catch him?

 

[Nah]

I think you might just have to talk to the man at the Weather Institute again to make the cave reappear. Prior to gen 4, I think that the only way to screw yourself out of capturing a legendary is to KO it and save afterwards, so I don't think that Groudon should be permanently gone for you.
