Official update history
Armbot was able to grab some hairstyles from the top shelf, and we figured, since we already paid for them, we should add them to the game!
- Added Hime Hair, Odango Hair, Blunt Bob Hair, and Baseball Cap
- Updated charm descriptions to say "when equipped"
- Updated “One step ahead“ skill - it can now draw any cards, not just attack cards.
- Bug fixed: Hairclip seems to be dropping from chests, so it then doesn’t drop from Waldo’s letter.

- Updated a bunch of NPC dialogue lines that weren't being triggered due to impossible trigger criteria
- Fixed a typo in Black Pearl description.
- Fixed a bug with scrolling in the Spirit Storage screen - when selecting the "Let go" option, the list was scrolled to the beginning, and another spirit became highlighted, and it wasn’t clear which spirit was being let go.
- After confirming the "Let go" dialogue, the list now stays in the same position, doesn’t scroll to the beginning.
We meditated by an Ando Tree and now Ando Acolyte works properly!

Happy April, dear ones! It's Magic Man, or Waldo, perhaps you know me as, yes.
In the old kingdom, the first of April was a most special day – a day for rejoicing in the strange, the arcane, the unusual – much like me, oho!
And I indeed have something strange, arcane, and unusual to show you today. In my magical experimentation, I discovered something most peculiar, revealed to me by my darling Fishbo Junior in whispers at night. I am calling them...
FISHBO VARIANTS.
You see, under the right conditions, a Fishbo can transfer its very essence to other Spirits, transforming them into Fishbo-like creatures, while still retaining parts of their own original essence, yes! These new Spirits sprout legs and grow bowls around their bodies, becoming as Fishbo, but still yet something... unique, and special. It is said that any Fishbo that appears in the world will have a small chance of being one of these mutations! How interesting, yes!
I hope you will find some of these rare and wonderful Spirits yourself, and you will say to yourself, "ah, Waldo, what a genius you are, yes!" And then I hope you will bring them to say hello to Fishbo Junior. It was his idea, after all.
Happy April, my dear ones! Ah, no, I already said that. Well, goodbye, then!
