How to earn Kubfu and have Pokémon follow you
You can earn the new legendary Pokémon Kubfu at the same time as you have Pokémon follow you around, so this is a nice two-in-one deal.
All you need to do for this is to follow the basic instructions given to you by the Dojo Master.
First, find and defeat Master's Slowpoke
Next, find Max Mushrooms in a cave to the North of the island.
Finally, defeat your rival.
Once all that is complete, the Dojo master will bless you with a Kubfu, and the ability to have a Pokémon follow you around in the new Wild Area.
How to evolve Kubfu
Alright, now you have Kubfu, and he'll likely be at a pretty low level compared to the rest of your party. He starts out at just level 10, which is going to be a problem.
After getting Kubfu you'll be tasked with befriending him. Making curry at Pokémon Camp and taking him to the viewpoints marked on your map will get this done quickly.
After that you'll have to take Kubfu through either the Dark Tower or Water Tower. He has to fight through five floors by himself, with very, very tough enemies. You'll need Kubfu to be at least level 60 or even 70 in order to do this, meaning you either need to start training, or hopefully you'll have plenty of Rare Candy…
Once one of the towers has been conquered, you can evolve Kubfu into Urshifu, and he'll have either a Dark or Water type depending on which tower you took on.
How to find Alolan Diglett
Alolan Diglett are absolutely everywhere on the Isle of Armor, and there are 151 to find. The first is simple, the rest are not.
Essentially you just need to look for the three little hairs sticking out of the ground. When you spot them, investigate, and you'll see a Diglett.
A nice concession is that the game lets you know how many more Diglett are in any given area, so you won't spend too much time looking in a cleared zone.
How to change your bike design
Once you've gotten a few things done on the Isle of Armor you'll find a nice lady outside of the Master Dojo, and she'll allow you to change your bike design into something either sleek and black, or polished and white.
Both look very cool, and have a nice particle effect which swirls around you as you ride through the world.
How to upgrade the Master Dojo
The Master Dojo has a whole bunch of upgrades you can earn via spending Watts, but you will need to spend a lot of Watts getting all of the upgrades…
Luckily the Isle of Armor has plenty of hotspots where you can earn extra Watts, and you can easily earn 10k at a time. That sounds like a lot, but you will need 200k before you get all of the upgrades.
The upgrades turn the Dojo into a nice hub area where you can do absolutely everything all in one place. Not a bad idea at all, especially if you've been stocking up on Watts since launch.
