Pokemon Sun and Moon has a demo out now that allows players to unlock the brand-new Ash Greninja for use in the full games once they release. However, there are other items that can be obtained and brought to the soon to release games. Here’s what they are and how to get them.
You can obtain three Stardusts in the demo that can be transferred in the game. To obtain these, you’ll have to go to the end of the road where the Pokemon Center is where you’ll find a bunch of Slowpokes blocking the path. When you reach them, talk to the NPCs to the left and you’ll find yourself at the Mahalo Trail. Using the Ride Pager item you obtain in the demo, you can smash through the rocks you find at the top where you’ll find these Pokemon Sun and Moon items.
You’ll once again need to break through some rocks to obtain this item, only this time it will be with a Tauros at Ten Carat Hill. This will grant you access to the Pokemon Catching Challenge, which is the only part of the demo that lets you catch Pokemon (although you can’t keep them). If you catch at least three, you’ll then be given the Nugget item.
This item is obtained in Ten Carat Hill. There are three trainers here for you to fight, and you’ll need to beat all of them. This will let you fight Ace Trainer Sheri who can be found in the beginning of Ten Carat Hill. She uses a Jangmo-o and a Pikachu. Beat them both and you’ll get this Star Piece.
These are the only items we know of so far, so be sure to check back in for more updates on Pokemon Sun and Moon.
