Hi there.... haven't seen you around for awhile 😊
I just had a look in my inventory backpack.....I also have some leftover items even though I have nearly finished 'Challenge 3".
From what I can work out....if anyone else knows.... please feel free to correct me
The 6 Pink Flowers just seem to sit there as you have already made the Elixir Of Transmutation....I've still got them in my inventory backpack too.
The Toilet Paper just seems to also sit there....it was next to the pile of paper that Diggy collected for the woman at the desk....Diggy picked up both the Toilet Paper & the pile of paper.....I assume the the woman at the desk only wanted the pile of paper not the Toilet Paper 😂🤣 maybe a funny covid reference
The Sword is needed in "Mystical Mountain"....you give it to the Prince so he can rescue the Princess....this is where you get a Birthday Key from.
EDIT: The Pickaxe is needed in "Bug Infested Land"....you give it to the Gold Miner in a tent.
The Elixir Of Transmutation is needed in the "Monsters Citadel"....you put it in the cannon to defeat the monster.
The Ladder & the Pigeons (birds) are need in "Challenge 2".....you need the Ladder to reach 1 Pigeon off the castle wall......there are 6 Pigeons to collect....you give the Pigeons to the old woman....EDIT: this unlocks the large group of rewards in "Challenge 2".
The 1 I'm not 100% sure about is the Spicy Soup.....I believe it's needed in "Challenge 2"......I think you put the Spicy Soup in the bowl for the less fortunate people living in the tent.
I think where the confusion arises in relation to the Spicy Soup is in "Bug Infested Land" when Diggy talks to Luc....she says "When I was collecting ingredients for this delicious soup, I lost my precious book, if you find it, please bring it to me".....Diggy needs to find the book for Luc & give it back to her.
Absolutely love the hilarious reference to "Chilli Out" from @Slanka.Pixel in the "Bug Infested Land" walkthrough article 🤣😂🌶️🥣
Unless the Spicy Soup belongs to a completely unrelated regional or story quest????
Here is a screenshot from my own game.
