Pokemon Sleep has over 100 Pokemon, a number that is lower than most Pokemon games, and some players might find it worrying. Although, given Pokemon Sleep's mechanics, it is for the best that there are not a lot of Pokemon. Aside from working on Snorlax's strength and increasing its Drowsy Power, players have to get their hands on different kinds of biscuits to befriend Pokemon.
Each day, players get one Bonus Biscuit or a Premium Bonus Biscuit, depending on whether they have the Regular or Premium Pass. Barring this one biscuit, players have to purchase biscuits manually. This makes it extremely difficult to befriend several Pokemon in one go unless players heavily invest money in the game.
For those who just want to enjoy, there is no reason to fret, as the Pokemon available in Pokemon Sleep are adorable, and they can even be evolved using different methods. Some Pokemon require hitting a certain level and having a certain number of candies. However, there are others who need a particular evolutionary rock to evolve. So, this guide will cover all the evolutionary rocks in Pokemon Sleep and where players can find them.
Thunder Stone
- A peculiar stone that can make certain species of Pokemon evolve. It has a distinct thunderbolt pattern.
The Thunder Stone can be found in the Regular Exchange, where it is priced at 1,400 Sleep Points. Players also receive it as a gift for getting ten Pokemon to level 45.
Fire Stone
- A peculiar stone that can make certain species of Pokemon evolve. It has a fiery orange heart.
The Fire Stone is available in Regular Exchange for 1,400. Players can buy five at one time, and like all the other evolutionary stones, they restock after the reset. The free alternative is to raise ten Pokemon to level 25.
Water Stone
- A peculiar stone that can make certain species of Pokemon evolve. It is the clear blue of a deep pool.
The Water Stone is another evolutionary rock that can be obtained via Regular Exchange. The free version requires players to get ten of their Pokemon to level 35, which will get them one Water Stone as a reward.
Leaf Stone
- A peculiar stone that can make certain species of Pokemon evolve. It has an unmistakable leaf pattern.
The Leaf Stone can either be purchased from the Regular Exchange or acquired once the team's RP reaches 1,900 or above.
Ice Stone
- A peculiar stone that can make certain species of Pokemon evolve. It has a snowflake pattern in it.
Players can get their hands on the Ice Stone by directly buying it from the General Store for a steep price of 1,400 Sleep Points. Another way of obtaining the Ice Stone is by raising the ten Pokemon to level 5.
Moon Stone
- A peculiar stone that can make certain species of Pokemon evolve. It is dark like the night sky.
Players looking to buy a Moon Stone can do so by heading to the General Store. They can also get it as a reward for making sure their team's RP is 4,700 or above.
Shiny Stone
- A peculiar stone that can make certain species of Pokemon evolve. It shines with a dazzling light.
The Shiny Stone can be bought for 1,400 Sleep Points. Alternatively, players can get one by getting their team's RP to 11,400.
