It seems like you're asking about the Sun Stone piece from the game "Time Tangled Island"! However, there is no mention of a Sun Stone in the game.

Could you be thinking of a different item or a different game? Perhaps you could provide more context, like:

* The specific game: Is it a specific game on a platform like Roblox or a mobile game?

* The item's location: Are you looking for a specific area on the island, or a specific task you need to do to get the item?
