StacyPlays organized the season once again. The server is hosted by LearningMonkey.
Unlike the first season, this season does not give the participants a wolf egg spawn and cake. Golden Apples (renamed as Golden Caramel Apple) can only be crafted by a (caramel) apple surrounded by gold ingots. The series follows the 2-day format, new episodes releasing every other day, starting on the premiere. Episodes continues to be 16 minutes long, like the previous season.
In the second episode, Team Dino joked about Pip3r winning, saying it would be funny if the first person to take damage won the game.
Netty accidentally leaked the first episode on October 09, 2015. A handful of viewers saw the episode before it became private. 
Mousie and Bee hinted the premiere on October 11, 2015 when they tweeted out that a new series will premiere on tomorrow (October 12, 2015).
This season is Halloween themed as many competitors wore costume on their Minecraft skin as well as the season being dubbed as "Boo!HShe". The participants were required to use a texture/resource pack that replaces item such as apples to caramel apples, torches as candy corn, etc.
The name of the resource pack where these textures were taken from is called Sugarpack
AmyLee requested to not team with anybody, so to make it fair she instead was given a cat as a teammate.
Casper is the first player to be an animal.
He is also the first male to compete.
On a few thumbnails, the UHShe logo is the same the the Golden Apple, but it resembles a pumpkin, referencing the season to be Halloween themed.
There is another logo that contains a blue Golden Apple in Cybernova's channel.
The intro sequence is similar to the first season, but uses a darker colors that correlates with the season.
Also, the intro has a film effect that resembles black and white movies.
MK and Aureylian are the only participants without custom Halloween skins.
Team Boogie is a reference to the previous season, when Mousie built her Disco House, which became the battle ground of the season.
Team Boogie was also used in another series, Outlive, where a handful of YouTubers play and try to out-live the remaining players, while gaining points, one point per minute a person lives. However, unlike Outlive, Mousie is teamed with MK, rather than Netty.
MK accidentally uploaded her first episode of the first season, so her first episode was uploaded two days late.
At the time, Pip3r and Squig are the only participants who aren't adults yet, making them the youngest participants and team to compete in UHShe.
Stacy met both players at Minecon 2015, when they appeared in a vlog. 
There are at least eight variation of the intro sequence.
The original song (Stacy's intro) are used by Stacy, Squig, Piper, Cupquake, Hannah, Mousie, Shubble, and Netty.
However, Netty didn't used the intro in their first episode, but in the later episodes; and Hannah used different intro music in later episodes.
Aureylian uses the same song, but her intro begins at a later part of the song.
Her intro, as well as the shortened version, contained a trumpet that can be easily distinguished which a majority of the roster uses after the first episode and onwards.
Kaleidow, Yammy, Salem, Amy, MK, and Bee used the same intro sequence but had different songs.
Bee and Kaleidow used the same song, but Kaleidow's intro was faster and louder.
While Yammy, Salem, MK, and Amy had all different songs.
Ashley and Lizzie do not use the intro whatsoever.
This season was originally going to include "Trick or Treat" Lucky Blocks, but it was later decided not to include them.
However, due to some kind of programming glitch, some Lucky Block temples still spawned in the world.
