Regigigas will appear as a statue and will not awaken unless the legendary golems, Regice, Regirock and Registeel, are in the party. The temple has six floors (1F to B5F) and has many puzzles involving sliding on ice and stopping on rocks, making the way through the temple. This format is similar to the Icefall Cave, Ice Path, and the Mahogany and Snowpoint Gyms.
A colored background means that the Pokémon can be found in this location in the specified game. A white background with a colored letter means that the Pokémon cannot be found here.
The Snowpoint Temple briefly appeared in A Pyramiding Rage!. Unlike the games, Maria is the Temple Guardian.
In Pillars of Friendship, the Regigigas residing in it went on rampage after J destroyed the three pillars which protected it. However, it was calmed down by the end of the episode. Brandon later released his Regirock, Registeel and Regice to undertake the position of Regigigas's guardians.
Trivia
In Platinum, when confronting Regigigas it is level 1. This makes Platinum the first game where level 1 Pokémon can be caught in the wild, and Regigigas the first legendary Pokémon to be at level 1 in the wild without the use of a cheatingdevice.
In both encounters with Regigigas, Confuse Ray is the only move that is not replaced in its moveset.
