Jerry's Workshop, also known as the Winter Island, is an island that is open during the whole season of Late Winter (~11 hours long) every 5 days and 4 hours, or during the whole month of December. However, during the bonus events the Winter Island will only be opened 3 hours, from 1 hour before the event to 1 hour after. The island can be accessed through the SkyBlock Menu, your own Jerry or the Event Stand in the Village. Jerry's is the only location where Winter Sea Creatures can be fished up.
During the Season of Jerry, Mount Jerry will erupt and release lava, Liquid Hot Magmas, and Magma Cubes. Players must defend the piles of gifts in Jerry's Workshop.
Mobs will begin to spawn and attack five piles of Gifts in the village on the 23rd Late Winter. Players must defeat the waves of mobs that spawn to protect the gifts. These mobs cannot be damaged by regular attacks, and instead must be shot at with snowballs. Once all the Magma Cubes have been killed, the event will end and the player may collect gifts from any remaining piles in the village. This event has 5 waves lasting a total of 1 hour.
Gulliver tasks the player with controlling a chicken by flying it through hoops in the sky. The race will end if the timer runs out, player touches the ground or leaves the chicken (e.g. dismounting the chicken by pressing Shift, using an Aspect of the End, etc.) Passing through Cluckpoints will grant the player rewards for the first time they are passed and increase the timer.
Every time the Winter Island opens, 20White Gifts are scattered across Jerry's Workshop, which the player is tasked with finding. Between SkyBlock years, the gifts change locations, but can generally be found in the same areas: behind lampposts, snow and on top of rooftops. If the player owns a Gift Compass, they can use it to point in the direction of the nearest undiscovered White Gift.
