Several Pokemon in Pokemon Sleep can only evolve with the use of evolution items, logging some hours of sleep with them, or evolving them during a certain time of the day. Read on for a list of all Pokemon that have special evolution conditions in the game!

All Special Evolution Conditions

Evolution via Evolution Items

Some Pokemon need to be exposed to evolution stones or certain items for them to evolve to their next stage.

Pokemon that usually needs to be traded to another player can evolve with a Linking Cord.

You can purchase these evolution items in the Regular Exchange store using Sleep Points, or get them from clearing certain achievements.

Do note that you also need the Pokemon's corresponding candy to fully complete their evolution requirements.

List of All Evolution Items and How to Get Them

Evolution via Sleeping

Pokemon that conventionally evolve via friendship in the mainline games, like some baby Pokemon, have a different method of evolving in Pokemon Sleep.

In the app, you need to include them during your sleep sessions and log a specific number of hours slept before they can meet the requirements to evolve. They also need their corresponding candy to meet the requirements.

Pre-Evolution	Evolution	Evolution Condition	Candy
Pichu	Pikachu	Log 20 hours of sleep with Pichu	x20
Igglybuff	Jigglypuff	Log 20 hours of sleep with Igglybuff	x20
Togepi	Togetic	Log 50 hours of sleep with Togepi	x20
Eevee	Sylveon	Log 150 hours of sleep with Eevee	x80
Cleffa	Clefairy	Log 50 hours of sleep with Cleffa	x20

Sleep Session Mechanics

Time of Day Evolutions

Some Pokemon need to evolve around a certain time during the day to reach their next stage.

Pokemon that need to evolve during daytime can do so from 6 AM to 6 PM, while those that only evolve during the night can evolve between 6 PM to 6 AM. To evolve these Pokemon, you only need to tap on the Evolve button within these time frames once you've fulfilled the other necessary requirements.

Note that you also need to log some hours of sleep with these Pokemon, which you can do by including them in your team during sleep sessions, and have the required amount of candy they need to evolve.

Pre-Evolution	Evolution	Evolution Condition	Candy
Eevee	Espeon	Log 150 hrs of sleep with Eevee, then evolve it during daytime	x80
	Umbreon	Log 150 hrs of sleep with Eevee, then evolve it during nighttime
Riolu	Lucario	Log 150 hrs of sleep with Riolu, then evolve during daytime	x80
Sneasel	Weavile	Evolve with a Razor Claw during nighttime	x80
