Marvel Rivals is bringing back Jeff's Winter Splash Festival with a completely revamped version. The event launches with the upcoming weekly update and features a new map called Jeffland, along with updated gameplay. Let's take a look at the event details and rewards.
Note: We'll keep updating this guide with more details once the event goes live on December 19th.
Jeff's Winter Splash Festival Event Duration
Jeff's Winter Splash Festival starts on December 18, 2025, at 1 AM PT.
How Jeff's Winter Splash Festival Works
Jeff's Winter Splash Festival is a 4v4v4 game mode where three teams compete to paint the most ground in Jeffland. All players use Jeff the Land Shark with the Cuddly Fuzzlefin event costume equipped.
You can choose between three different Jeff builds, each with unique abilities. Jeff's skills are modified so that any ground sprayed will be painted with your team's color. The percentage of the arena each team has painted appears at the top of the screen. The team with the highest percentage at the end wins.
All Jeff's Winter Splash Festival Rewards
The event rewards haven't been officially confirmed yet, but the Cuddly Fuzzlefin costume for Jeff the Land Shark will likely be available along with new color variants. We'll update this section once the full reward list is revealed.
You can also earn more free skins right now with the ongoing Seeds of the Gardener event and Season 5.5 Twitch Drops for Iron Fist. The Seeds of the Gardener event offers a free Iron Man Mark I costume, while premium pass holders can unlock Iron Fist Shenloong Champion and Captain America Capwolf skins.
This week's update also brings the Winter Holiday 2025 event with seasonal costumes for Squirrel Girl, Daredevil, Winter Soldier, Peni Parker, Star-Lord, and Thor, along with a new mystery burger at Pym Technologies Test Kitchen in Times Square.
