Pokémon Ranger/Escort the Professor!

Back at Base
Spenser will congratulate you on your work during your first mission. He then asks that you and Solana/Lunick go patrol the town until you find a mission. Go out of the Ranger Base, and you will hear a Pokémon's cry. Minun is being chased by Larry's Taillow! You enter a capture to calm the 2 Pokémon down.

Minun/Plusle
You are introduced to Minun/Plusle's assist, which launches some electric rays in multiple directions, paralyzing anything they touch for a short amount of time. Capture the Taillow while it's paralyzed.

You find out that Minun/Plusle started harassing Taillow as it was jealous of how much care Larry gave it. Minun/Plusle goes to apologize to Taillow, and Larry comments on how it seems lonely. You and Minun/Plusle will form a connection, and Minun/Plusle's data will be registered in your Browser. You now have a partner Pokémon!

"Patrolling"
Though you can talk to the NPCs around town if you'd like, there's not actually any need to do any more patrolling, so you can head back to the Ranger Base.

Spenser notices that Minun/Plusle from before came with you, and immediately understands the situation. Solana/Ludwick then explains how your Minun/Plusle's ability works, since their partner's ability is much the same.

Partner Pokémon
As is explained during the tutorial, your partner Pokémon has a sort of "infinite" assist. Every time the bar under your Styler's health charges all the way up, you can use the Paralyze assist that you saw earlier used on Taillow. The bar is filled by drawing loops around the Pokémon you're trying to capture, and the filled amount will transfer between battles, so you don't have to worry about it resetting.

It's also worthy of note that, as your Ranger Rank goes up, your partner's assist will become stronger, adding more bars that allow you to charge the assist more and more.

Professor Hastings
After the tutorial, Solana/Lunick goes back to patrolling. Then, an old man walks into the Base. This is Professor Hastings, and you can just hear him and Spenser mentioning something about a Super Styler. While they're talking, Spenser asks that you go upstairs and check on his Fearow. Go upstairs and tap on Fearow. The Ranger taking care of it says it's resting, and can't carry the Professor home, so go back down to Spenser.

He says that he has a new mission for you: You must escort Professor Hastings back to Fall City without anything happening to him. This is your first official mission, to go through Lyra Forest and Krokka Tunnel to get to Fall City. Go to Lyra Forest.

Lyra Forest
As you enter the forest, the mission will begin, and you will immediately be attacked by a Bellsprout.

After you capture it, Professor Hastings will explain to you how Bellsprout's Poké Assist works. In short, when you draw a line while having the Grass Poké Assist active, your line will be covered in tall grass, which, if touched by a Pokémon, will immobilize them for a short while.

Going north, you will find a Mudkip and Hastings will explain how the Water Poké Assist works. With the Water Assist, if you tap and hold in 1 place with the stylus, you'll grow a bubble. The more time you hold, the bigger the bubble. You can then flick this bubble at the Pokémon you're trying to capture and it will remain trapped in it for a short amount of time.

After these tutorials you'll be free to explore the forest with the extension to the north that you couldn't access before. You can now capture a few more Pokémon. Pokémon in this area (Bold = New):

As you head north, you want to catch a Torchic that's to the west of the kid with the backwards hat. You'll see some haybales in your path, and tapping on them allows you to see they take a Field Move of to clear, so use the Torchic you captured.

Continuing down the path, you'll find Pichu and, if you continue until you see a log blocking your path, and then head back down, you'll encounter a Combusken. You may also find some bushes that require to clear, which you don't have access to yet, so ignore those.

Use the captured Combusken to clear the log in the way, and head up into Krokka Tunnel.

Krokka Tunnel
Pokémon in this area (Bold = New)

Heading into Krokka Tunnel, you'll only be seeing Bellsprout in this first room.

If you head to the right then through the exit at the bottom, you'll see a guy with some Magikarp, but you can't do anything here yet, so head back into the cave and through the opening at the top.

Heading into the next room, you'll see a Dugtrio, but it'll flee as soon as Hastings goes near it. Boulders will fall, separating you from the Professor, who then requests that you find a way around to him. A couple new Pokémon will now be available.

Capture the Paras and use it to cut down the Fence. You will then be able to capture Magnemite and progress to the east. In the next room you'll find another new Pokémon, Poliwag.

Heading through the linear path, you'll end up encountering 2 members of Team Go-Rock, who steal the Super Styler from Professor Hastings. You chase after them, but they end up managing to escape.

(WARNING: If this is your first time playing the game, it is recommended that you use the Save Machine that's right before the exit of the tunnel. Having a Pokémon that has the Water Assist, like Mudkip or Poliwag, is also recommended. Lastly, make sure you know how to use this Assist relatively well.)

Going outside the cave, you'll see a rampaging Rhydon. This is your first "boss battle", and you cannot escape from it. If you have a Water Assist, it is recommended that you use it for an easy capture. If not, simply be careful for Rhydon's attacks, looping only while it's not throwing boulders, and being careful of its charging attack.

After the capture, you'll immediately release the calmed Rhydon. However, you've finally arrived at your destination, so go east to reach Fall City. You'll have to release every Pokémon you had kept up to this point besides your partner so that they're not removed from their habitat.

Fall City
Not much to do here right now, just go right until Hastings stops you to say that, even though his Super Styler was stolen, you still managed to protect Hastings himself from any harm, and so you did what you were asked to do wonderfully.

Mission Clear!

Joel, the leader of Fall City's Ranger Base, will come in on his Dodrio. Hastings informs him of what happened with the Super Styler, and you go into the Ranger Base to talk about what happened.
