It's about time for some limited time collaborations on the Green ver. firware to spice up your Donder life! Note that both of the campaigns are just on teaser status for now, and you should stay tuned for more details (by official channels, or us!) if you are interested.
First up, as the header image should hint, is Sanrio's Gudetama (ぐでたま), currently only teased with a special page on the AC0 main site and an explicit collab period (September 4 to October 7 2019).
The main collaborative happening is the addition of two songs to the AC0 song list, and then the chance to win collab-branded merch just by playing those songs. Further details are slated to be released on August 25 2019.

If you feel too groggy (geddit?) after the first collab, then how about letting some energetic idols to cheer you up? Particularly nine of them?
After a well-received collab in 2018, the idols from IDOLiSH7 are returning to Taiko no Tatsujin scene in 2019 (no approximate date/timeframe given). In addition to the usual new song additions, expect the grand return of Taiko no Tatsujin Cheering Squad (太鼓の達人応援団) with four new members joining the festive fray. If you are well-versed in IDOLiSH7 lore, maybe you can guess who they are from the new silouettes in the teaser tweet above?
