Hey guys,
I have decided to make a list of all the NPC's who say you have to meet them in X days.
If I missed someone please correct me so no-one will miss whatever goodies they give us.
These days are counted from the day the demo was released, if someone wants to add specific dates to them, feel free to do so.
Day 1 (Not timed), Tauros ride 3 stardust. (Talk to the lady at the far end of the road with the Pokécenter) (Any date) On the route towards the trial, beat all 4 trainers and you will get a star peice. (4th one is kinda hard as she has an electro-ball Pikachu)
These are timed:
Day 2, talk to the guy outside of the Pokécenter (19-10-2016)
Day 6, lady wearing a straw hat at the corner south of the Pokécenter (23-10-2016)
Day 13, old man inside of the city hall (31-10-2016)
Day 19, Police man on the docks of the marina, backtrack right of the city hall and go down (6-11-2016)
Day 25, woman inside of the building at the marina docks (12-11-2016)
PLEASE CHECK IF THESE DATES ARE RIGHT!
As far as I can see, after having talked to every NPC after completing the trial these are all timed events.
Fun fact: if you battle a trainer while on Tauros you wear the 'safety clothing' during the battle, thought this was a nice detail to tell. :D
I'm not sure if someone mentioned it, but Pikipek learns Rock Smash too
Rockruff also learns Rock Throw & Bite, I caught one in the mini game. Yungoos also has sand-attack and bite.
EDIT: Judging on the pokémon I caught: Pikipek has decent speed, quite high attack and decent rest. Yungoos, mine was modest, but he has surprisingly high attack, rest is super decent (same speed as defenses). Rockruff, mine was brave, but he has decent attack and high speed, surprisingly Rockruff has less attack than yungoos.
