In New Horizons
Bunny Day is the first seasonal event to occur after New Horizons's release, and unlike in previous installments, lasts multiple days from 1st of April, 2020 to 12th of April, 2020 . Zipper appears on on the island on the first day to tell the player about the event and give the Bunny Day bed recipe; if the player misses Zipper, the recipe will arrive in the mail the next day.
As before, there are 6 types of eggs to collect, Sky (Found hanging on multicolored balloons), Water (Found via fishing), Leaf (found in groups of 3 on trees and needs to be shaken off), Stone (Found by hitting a rock with a axe or shovel), Earth (Found in the ground like fossils), and Wood (Found occasionally by hitting a tree with a axe). These eggs are used to craft items in a new series, the ¨Bunny Day Series.¨ Like in New Leaf, the eggs can be eaten, which provides stamina in the same way as eating any fruit.
Players can also learn unique DIY recipes for a hat, dress, and shoes themed around each type of egg after collecting a certain amount of eggs of that type. Collecting all of the egg-themed costume recipes unlocks the recipe for Egg party hat and Egg party dress.
These DIY recipes can be found in a few different ways:
In presents tied to multicolored balloons in the sky (the same ones that drop sky eggs), needing a slingshot to get them. This seems to be the most efficient way of gaining recipes as about 1/3 of the multicolored balloons will be a recipe.
In a multicolored variant of the message in a bottle called an Egg message bottle.
From villagers who upon seeing the player have an ! above their head and run towards them.
Four recipes (Bunny Day bed, Bunny Day arch, Wobbling Zipper toy, and Bunny Day wand) can only be obtained from Zipper himself.
On Bunny Day, Zipper will be present in the Resident Services plaza and all villagers will be dressed in egg costumes when they are outdoors. The player can obtain the Bunny Day arch recipe by speaking to Zipper. From then on, Zipper will also allow the player to trade in 3 of any type of egg for 1 of any other type, and also exchange 1 of each type of egg together for a Bunny Day basket furniture item, which has no DIY recipe.
Upon finding and crafting every single Bunny Day DIY recipe, including the Bunny Day arch, talking to Zipper again will reward the Wobbling Zipper toy recipe. After crafting that recipe and returning to Zipper for a third time, the player will receive the final prize of the event: the Bunny Day wand recipe.
