When the full game launches, you can talk to Professor Kukui to send everything over to the full version.

Star Piece - Defeat 3 trainers at Ten Carat Hill, then talk to the Ace Trainer near the beginning.

Nugget - Catch at least 3 Pokemon in the Pokemon-Catching Challenge.

Break through all the rocks and head to the top of the hill to start a conversation with the mysterious old man, who gives you the reward.

Talk to the girl on the left to take you to a special place where you can ride Tauros.

Stardust x3 - Go south of the Pokemon center until you hit the path blocked by Slowpoke.

Ash-Greninja - Complete the photo trial/main portion of the demo.

Playing the demo not only lets you get a glimpse of the game, but you can get rewards to send to the full version. I suspect that in the full version, you will be able to swap out Pokemon you get and send the others to your PC. The demo does not allow you to keep any Pokemon you catch, so it will ask if you want to 'Send Home to Nature'. While doing the Pokemon Catching Contest, you can switch out a Pokemon if you have 6 with you already. You must fight 3 of them before you can fight the 4th.You must send back all the Pokemon when the contest is over.You can catch Yungoos, Pikipek, Rockruff, and Pikachu.This is a challenge where you get to catch different Pokemon, but you only have 16 Poke Balls, 3 Heal Balls, and 1 Great Ball.You can participate in a Pokemon-catching challenge.

You get a Ride Pager that lets you ride Tauros and smash through rocks to open new pathways.You use the Professor's Pikachu and try out the Z-Move Gigavolt Havoc during a special fight.

You get to do a Trial that involves taking pictures of 4 Pokemon.It also increases the damage of Water Shuriken. This can turn into Ash-Greninja once your bond gets high enough in battle.You fight with a Greninja that has Battle Bond.This section will go over everything you can do in the demo. I'm going to go over everything in the demo so you don't miss a thing while you get prepared for the launch of Pokemon Sun and Moon. You can also get a special Greninja to transfer to the full version if you complete the demo, so it is a good idea to get this.
