Seasonal Events

Fall

Halloween-themed skin filter event.

When applied, it would turn creatures different shades of orange, green, purple, black, and white.
It could be disabled by disabling seasonal-themed skin filters in settings.
It was only active on Halloween.
The Halloween-themed skin filter did not return after 2020 due to complaints of it ruining people's skins.

Seasonal Winter Snowflake Parasaurolophus Skin event.

This event ran from December 14th, 2022 to January 1st, 2023.
This skin was able to be unlocked by growing a Parasaurolophus to Gauntlet age (1.32) on any server running the Life Cycle game mode.
This skin is no longer obtainable as of January 1st, 2023. It's possible it will be able to be earned again in future events.
When the skin was unlocked, a notification for earning the Winter skin would display, granting the player the ability to select and use this skin.
It will always be available to the player on any server once it has been unlocked. Originally this was not the case, and the skin had to be unlocked on a per-server basis.
The dusting of snow on top of the model can be toggled on or off in the character tab.
The skin is fully customizable - including the colors of the blanket - and has a glowing snowflake layer on said blanket.
When the achievement system was implemented, an achievement for having earned this skin was granted to every player who had done so.
