If you see the end of UTUA, then you are aware that there will be a sequel called "Ghost Mayhem". I am working on that and I have two chapters finished, but it will be a while to post them because I want to see the flow of it before I post the early chapters. In a meantime, here is the summary:
Sequel to Unlikely Team, Unlikely Allies.
Onion Cookie can control her ghost powers which help her gain confidence in herself and from her fear of ghosts. She is happy yet feels that GingerBrave is distant towards her and they will have to deal with the adventures together in a city called Candle City for the Ghost Festival, where unexpected ghosts happened and secrets unravel facing new and old enemies. Will Onion Cookie and GingerBrave settle their issues for the fate of the city?
Many characters from both OB and K will appear, but I will tell you the important main characters: GingerBrave, Onion, Strawberry, Wizard, Eclair, Blackberry, Licorice, Pirate, White Ghost, Candy Diver, and Dozer.
The settler cookies will also return in this fanfic...and many fanmade cookies serve as minor roles in the series including the main antagonist, Candleworks Cookie.
You can ask for some info if you are curious.
