Pokemon black version How do you move the gray rocks in front of legendary trios caves?

You can't move the gray rocks in front of the Legendary Trios' caves in Pokemon Black. Those rocks are permanent obstacles designed to keep you out of those areas until you've progressed further in the game.

Here's why:

* Story Progression: The Legendary Trios (Cobalion, Terrakion, Virizion, and the other three) are powerful Pokemon that are meant to be encountered later in the game. The rocks act as a barrier to prevent you from encountering them too early.

* Difficulty Balance: These Legendary Pokemon are challenging, and having access to them too early would disrupt the intended difficulty curve of the game.

To reach the Legendary Trios, you need to progress through the main story, complete certain tasks, and acquire specific items. Once you meet the requirements, you'll be able to access those caves and face the Legendary Pokemon.

To unlock the areas with the Legendary Trios, you'll need to:

1. Beat the Elite Four and become the Pokemon Champion.

2. Complete the "Legendary Pokemon" side quest. This quest involves gathering specific items and visiting specific locations, and it will eventually unlock the caves.

Good luck on your journey to encounter the Legendary Trios!
