— the Slimepedia
Ornaments are small spherical decorative items first introduced in the Wiggly Wonderland update, with a second batch introduced in Party Gordo Update, and three more added with The Optimization Update. There are currently 38 different designs available in the game.
Any ornaments obtained will remain after their associated event is over, and can be kept.
Ornaments are unique decorations which can be found in party crates or during special events. There are dozens of different ornaments to find and collect, but only a handful of designs seem to be available at any one time. They're fun to collect but... who is making all of these ornaments and hiding them around the Far, Far Range? Probably best not think about it too much.
On the Ranch:
Ornaments make great decorations for any part of your ranch. Vac them up and shoot them wherever you'd like. They stick to just about anything and can even float in midair!
Ornaments are exclusively obtained from time-limited events.
Main article: Wiggly Wonderland
The first fifteen ornaments were introduced during the Wiggly Wonderland (2017) event, which ran from December 20th to January 1st.
Main article: Party Weekend
Twenty more ornaments were added in the Party Gordo update which introduced the Party Gordo and its associated party-themed crates which appear while the Party Weekend event is active. Two ornament types were made available per week, with a low chance to receive a rare ornament instead.

- All of the ornaments are based off real-world baubles.
- All of the ornaments appear to have Echoes inside them.
- According to Ian McConville, the ornaments use a shader comparable to an N64-era effect in its simplicity. 
- It is not possible to obtain the ornaments through normal gameplay outside of the allotted dates. However the game runs off of the computer's clock, so the system's date and time can be altered to appear within these dates. Restarting the game is not required.
- Manually adjusting the system clock to hunt for ornaments could cause problems with Slime Rancher's backup save system and Steam Cloud saves. Do so at your own risk.
- Until Update 1.3.1, it was not possible through normal gameplay to obtain Briar Ornaments on any date. This has since been changed; it is now obtainable on November 16-18 2018 (replacing the elder ornament that held the common slot prior to 1.3.1) and April 26th - 28, 2019.
- Party Crates can remain after a Party Weekend event; finding and opening a party crate on a date outside of party weekend will always yield a Pink Ornament or a Rare Ornament.
- The insides of the ornaments seem to be echoes of non-existent colors.
- The Pink? and Tabby? ornaments appear to have facial expressions based off of the popular transform pokemon; Ditto.
