The Scroll Ingredient is an incredibly rare item that was released with the Monkey Fairground Event in Adopt Me! When players combined this ultra-rare ingredient with three other Monkeys, they were transformed into a Ninja Monkey. This item is quite hard to come by, as it has only a 10% chance of being acquired from regular Monkey Boxes and a 20% chance from the Premium Monkey Boxes.
Once the event is over, players cannot exchange their Scroll Ingredients for a Ninja Monkey. The only way to obtain this item now is through trading with other players or by unboxing any remaining Monkey Boxes. The Scroll Ingredient is incredibly valuable, as it could transform a Monkey into a Ninja Monkey, so it's important not to miss the chance of acquiring it if you come across it.
