Basically, if I’m out fishing and I catch an angelfish, I buy an aquarium. I also grow death flowers.
I… have issues, okay? Life insurance! give me life insurance!
You can also buy them during the Sulani fishing competition on Saturdays, from the little fish/bait shop.
I also have two retail stores in my current save where ambrosia is for sale:
1. Jenna’s magic shop, available in the gallery. I couldn’t figure out how to sell fish, but most other potions, ingredients, and tomes are there. Also dragonfruit, a money fruit, and ambrosia. (I think the gallery version has no ambrosia, come to think of it.)
2. Caleb’s oddities: I decided to pretend Caleb Vatore is “the oddity collector” from the Paranormal Stuff pack. He has specter gifts, vampire tomes, some werewolf items, the cure for vampires and werewolves… and ambrosia. (He lets the witch across town do the witch stuff.) I don’t remember if I ever uploaded this to the gallery or not…
