Full details revealed on Pokémon Sleep's two week long Entei Research event, running May 20th through to June 2nd

As announced at the end of last month, Sleep Researchers will soon be getting another opportunity to observe the sleep styles of a Legendary Pokémon in Pokémon Sleep, with the two week long Entei Research event scheduled to commence Monday May 20th at 4:00am local time, and running through to Monday June 3rd at 3:59am local time.

To participate and gain bonuses and rewards from this event, Researchers will need to conduct their sleep research for these two weeks on Greengrass Isle, with the following bonuses active throughout the event period:

• Each time when Fire-type helper Pokémon bring ingredients, they will one extra ingredient
• Fire-type helper Pokémon's main skills are ×1.5 more likely to be triggered
• Researchers can encounter a few Pokémon of different sleep types regardless of their own sleep type for the day.

The following additional bonuses will also be available during specified periods

• 1st Week of the Event (May 20th through 26th): Main skill levels of Fire-type helper Pokémon will be boosted by 1 level
• 2nd Week of the Event (May 27th through June 2nd): Main skill levels of Fire-type helper Pokémon will be boosted by 3 levels
• Second Sunday of the Event (June 2nd): Drowsy Power will a ×1.5 bonus

Sleep tracking on any other map will not trigger these event bonuses. Snorlax on Greengrass Isle during this event with have Leppa Berries set as one of its favorite Berries. These berries can be found on Fire-type Pokémon, so Researchers will want to take full advantage of the Fire Type Week event starting next week on Monday May 6th to prepare their party.

Additionally, the following Pokémon will also appear more frequently during sleep research on Greengrass Isle throughout the event:

• Slightly Greater Appearance Rate
  • Charmander, Charmeleon, Charizard, Vulpix, Ninetales, Growlithe, Flareon, Cyndaquil, Quilava, Typhlosion, Entei

Similar to the previous Raikou Research event, Researchers will be collecting samples of Entei Mane to redeem for a variety of valuable items in the Event Exchange, including Main Skill Seeds, and Fire Stones, as well as items specifically intended to help Researchers befriend Entei. Entei Incense will work like any other species incense, ensuring that Researchers will meet Entei during their next sleep research. Unlike other Incense items, players will be limited to one of this incense in their bag's item pocket at a time. Entei Biscuits meanwhile are a special blend of biscuit only able to be used with Entei, increasing its friendship points by 6. Following the conclusion of the event, any leftover Entei Biscuits will be automatically converted into Great Biscuits.

Compared to the previous Raikou Research event, Entei Main samples will be more readily available. Methods of obtaining Entei Main samples have not changed however, with the main way to get samples being from daily sleep research. The exact number of samples received by Researchers will depend on the species of Pokémon sleeping around Snorlax, and the sleep styles that Researchers find them in, with Fire-type Pokémon granting greater amounts of Entei Mane samples than other species. In addition, Researchers will also be able to collect Entei Mane samples from completing a set of special limited-time missions that will be added on top of the standard weekly missions, and as a rare reward from the Research Community. Researchers unable to access the Research Community screen will receive limited-time special gifts of 70 Entei Mane samples at the beginning of each week of this event, on May 20th and 27th.

Entei Mane samples will also be available for purchase with the Entei Research Bundles Vol. 1 and Entei Last Chance Bundles Vol. 1 from the in-game shop. More details on these bundles will be released at a later date.

The Event Exchange will be open between Monday May 20th at 4:00am local time, and Thursday June 6th at 3:59am local time. Prices for items in the exchange will vary during the event, with discounts on Entei Incense and Entei Biscuits in the event's second week.

Researchers should also note the following for this event:

• The daily rollover for the Entei Research event is at 4:00am local time.
• Event bonuses for this event apply only for sleep data tracked on Greengrass Isle.
• Event bonuses apply only for sleep tracking that begins within the event period, and do not apply to sleep tracking during the tutorial, or to sleep data tracked before the event, even if the researcher waits to review their sleep research after the event has started.
• Sleep data tracked during the event will receive event bonuses, regardless of if the researcher waits to review their sleep research until after the event has concluded.
• The bonus that raises Fire-type helper Pokémon's main skills is capped at the normal maximum level, and cannot surpass it. In some circumstances, Pokémon already on the team before the commencement of the event may not always trigger this bonus the very first time their main skill is triggered during the event.

Entei is a Snoozing Sleep Type Pokémon appearing exclusively at Greengrass Isle, and will start appearing for sleep research sessions commencing after May 20th, at 3:00pm local time. Entei is the second Pokémon Special Pokémon in the game. While Researchers may befriend any number of these Pokémon, no more than one of each species of Special Pokémon can be on a Researcher's team at any given time. The Nature and sub skills of the first Special Pokémon befriended of each species will also be identical for all Sleep Researchers.

Entei's main skill is Helper Boost (Fire). It is presumed that this will function in the same manner as Raikou's Helper Boost (Electric) skill, such that when this skill is triggered, a Researcher's full team of helper Pokémon will instantly gather a number of bonus Berries and ingredients depending on the level of the skill, and the number of different species of Fire-types on the team.
