what is in the ice thing behind the gym

It is snopoint temple, it is the home of the legendary Regigas, you can only get in once you have completed the national pokedex and have beaten the elite 4 at least once. To awaken regigas you need to have Regice, Regirock and Registeel in your party.

Hope this helps =)

Okay, by 'thing' I am assuming that you mean the building behind the Snow Point City Gym correct? Because if that is what you mean, then that building is the Snow Point City Temple. Home to Regigigas, king of Regice, Regirock, and Registeel. You can only go in there after you have beaten the Elite Four, and obtained the National Pokedex by seeing all 150 Pokemon in the Sinnoh Region. Regigigas will be on level 70, but in order to battle him you must have Regice, Regirock, and Registeel in your party.

Hope this helps.

The building behind you is the Snowpoint Temple, a building that you can not enter unless you 1. Have beaten the elite four 2. Have seen or caught all 150 sinnoh region Pokemon, and 3. Have migrated regice, registeel, and regirock to your diamond or pearl version via ruby, sapphire, or emirald through pal park. Anyway, after you have completed those three things, then you will enter the temple. Bring many ultra balls, timer balls, and repel, and maybe an escape rop or 2, because it gets pretty weird down there. On the final floor, you will see Regigagas, leader of the Golems, in the middle of the room. To fight/catch him, you need the three legendary Golems in your party, and some high level Pokemon with status affects, cause he takes FOREVER to catch.

Hope I helped :-)

Hat is the Snowpoint Temple, I assume. To enter you must first defeat the Elite 4 and get the National Pokedex. In this temple is a legendary Pokemon known as Regigigas. There's a statue in the temple. That Statue is the true Regigigas! To unlock the Statue, you must have the 3 necessary pokemon: Regirock, Rigice, and Registeel. To obtain these Pokemon, you must Migrate them. Where do you migrate them you ask? You could migrate them from R/S/E/FR/LG into the Pal Park. ( Where you could capture them. ) The Pal Park is still being fix, but you must first defeat the Elite 4 and obtain the National Pokedex for the Pal Park to open.

Hopes this helps ya'. ~DNL

The ruins? That's where you can catch regigigas after you beat the game. But you need the three regis
