During The Event:
Part 1: Aueko
Part 1 was released on April 7th. Upon the release of the event, the Aueko was added to the Easter Shop. Two new palettes, Tulip and Easter Egg, were also added to the game. The map additionally received event-related props, both for aesthetics and minigames. Alongside the release of the event, Polymonstrum was remodeled.
Scrambled Eggs Minigame
The scrambled eggs minigame can be initiated by interacting with the Broken Egg in the middle of the map. Once started, the player must interact with 6 egg pillars in the correct order. There will be a message in the chat that indicates the biome where the next pillar can be found, and a colored beacon will also shine from the pillar's location.
The player has 5 minutes to find the pillars in the correct order, and upon completion this minigame rewards 
40 Eggs. This minigame has a 2 minute cool down. A fast creature with flying/gliding capabilities is recommended.
Egg Hunt Minigame
The Egg Hunt minigame can be initiated by interacting with the Basket of Eggs in the middle of the map. Once started, the player must find 8 eggs in areas near where herbivore food may spawn, similarly to previous events. As such, these Eggs can also spawn on top of water, but that is a rare occurrence. The player has 8 minutes to find these eggs and claim them. These eggs are supposed to be for the most part client-sided to reduce LAG and prevent other creatures from stealing them. When the timer goes down to 2 minutes and 30 seconds, eggs will shine a beacon into the sky to make locating them easier, regardless of having Springram plushie equipped or not.
Usually during the Egg Hunt minigame more than 8 eggs can be found (usually 10-12). These eggs tend to be extras to help creatures with a reduced mobility type when some eggs have spawned at a hard-to-reach area, reducing the chance of having all 8 eggs at hard areas, and in case of having several close enough, get more than 8 eggs per quest before they disappear. However sometimes some of these extra eggs found are "Bad Eggs". These bad eggs are empty, do not count for the completion of the mission, and do not give any prompts on screen.
Upon completion, this minigame rewards 65 Eggs, plus an additional 3 Eggs for every egg collected. This minigame has a 2 minute cool down. A fast creature with flying/gliding capabilities is recommended.
Nesting

Notes About Plushie Use
Springram
As noted from a message sent by Acidant in the Official Discord Lobby, the Springram plushie will only double nesting rewards, not minigame rewards. Sniffing with the Springram plushie will also automatically enable beacons during minigames. It also still allows sniffing of tokens as before this Event released.
Eggshell
The Eggshell Plushie boosts nesting speed by 1.5x.
Part 2: Demetyra
Part 2 released at 14th April 2023 and added Demetyra, two new event material palettes (Egg Yolk and Easter Bunny), and a new minigame to replace the abscence of a boss battle. Additionally, Moonelle and Ovufu returned.
Alongside this part, Aesmir was added to the Galaxy Gacha, Aueko's glimmer was fixed to be visible, and some bugs related to the UI were corrected (freecam breaking the UI, and sometimes unwanted clicking sounds over menus).
Easter Matching Minigame
The Easter Matching minigame can be can be initiated by interacting with the Portal in the middle of the map. Upon interacting the creature will be teleported to an Easter Arena high in the sky, seemingly identical to the one seen in Easter Event 2022. Upon entry other players in the arena become invisible and cannot interact with each other (nor nest inside the arena), albeit someone seeing the arena from outside can spot and scent them; and 8 pairs of menhir (a total of 16, in two concentric squares, the inner with 4 menhirs) will gain a colored inscription that will match the inscription on another menhir. The quest consists on interacting with each menhir to select 7 matches in 6 minutes. For every pair completed another additional 2 eggs are added. Trying to make a wrong match will only reset the two selected menhirs and won't affect the match progress nor the final reward, and you'll have to interact with another pair; while interacting with an already selected menhir will not change anything apart from appearing a text message reiterating you must select a matching pair.
Upon completion it awards 40 Eggs (50 after part 3) and a cooldown is enabled.
Part 3: Fabraashe
Part 2 released at 21st April 2023 and added Fabraashe and two new plushies: Chick and Cow. Additionally, Buff Eulopii and Verdant Warden returned for the event. No new minigames were added.
Alongside the event, Rotation Store was changed to add a new rarity (Epic, in-between Rare and Legendary) and making all prices beyond Rare more expensive, and Tornir was added in that Rotation Store, with other rotation store creatures being re-shuffled into that category.

Trivia
- When Part 1 of the event released, the timer for the Scrambled Eggs minigame was originally 3 minutes and 30 seconds. It has since been changed to 5 minutes.
- Similarly, the timer for the Egg Hunt minigame was initially 6 minutes, but was changed to 8 minutes during part 1.
- This is the first event which upon release changed the effects of its event-related plushies (Eggshell and Springram plushie on this case).
- This is also the first Easter Event minigame where aquatics cannot join to the arena by staying below the teleport area.
- This is also the first Easter Event lacking a boss.
