Pokémon Red and Blue/S.S. Anne

'This ship caters to some of the world's most renowned Pokémon trainers. In fact, the S.S. Anne is on its annual Pokémon Cruise, where amateurs and professionals meet for a series of duels. Though not a trainer himself, the captain will give you Cut (HM 01), which will allow you to hack through the bush that blocks your path to the Vermilion City Gym.'

All aboard!
Flash your S.S. Ticket to the guard stationed at the docks, and you'll be allowed onto the massive S.S. Anne cruise liner.

If you want to get straight down to business, take stairway C, and then stairway E all the way to the Captain's cabin. But be forewarned: Your rival is after the same thing, and he'll be ready for a fight when you cross paths.

The rest of the ship is entirely optional, but you may find it worth your while. Worth noting is that if you don't do the rival battle and see the captain first, you can go on and off at your leisure. Stop in the kitchen (B) and root through the trash for your first Great Ball, a powered-up Poké Ball.

Down in the basement, the Sailors may not give up as much cash as the Gentlemen, but they're a snap if you have strong Electric or Grass Pokémon, and their prizes include TM 44, which contains Rest, a skill that can be learned by virtually any Pokémon. It completely fills that Pokémon's life bar, but puts it to sleep in the bargain, so only give it to a Pokémon (like Jigglypuff or something) that's tough enough to survive the beatdown it's going to receive while asleep. NOTE: In Basement 1, Sailor 1 in the chart is the one on top. On the image of the Upper Deck, the Sailor marked as 2 is not a trainer. The burly guy in the top left corner is actually Sailor 2, so don't let that surprise you. In the very last room in the basement, if you go up to the very top and press looking towards the pillow on the bed, you will be awarded with a Hyper Potion!





Before you can meet the captain... Rival Battle #4
Your Rival makes another appearance and demands another battle. Arguably, this battle is the easiest of all the Rival battles. While you had Routes 24, 25, and 6, plus the rest of the S.S. Anne and Cerulean Gym, to raise your Pokémon some 5-6 levels from where they were after the last fight, your Rival raised his maybe two apiece. And he didn't even add anyone.

What this means is that your strategy for all versions remains basically the same. Use Pikachu on the bird, Mankey in Yellow against the Normals, etc. However, you should have added three more Pokémon since that fight: a Grass-type (Bellsprout/Oddish), Diglett and Kadabra (by evolving Abra). As such, you can use a new strategy, assuming all your Pokémon are L22+.

Pidgeotto leads. Pikachu KOs it with a Thundershock or two, same as always. The next part is the only trouble spot: his Abra evolved, meaning it's actually a threat. Fearow is up to the task, fortunately; it should be faster, for starters, and it has Peck and Fury Attack running off of a high Attack hitting a low Defense. Just attack with Fearow and KO it quickly. Raticate is next, and while it still has the obnoxious Hyper Fang move, it has ceased to be a noteworthy threat. Use a fast, hard hitting Pokémon (recommend Kadabra, Fearow, or Diglett) to kill it in one hit, before it can start being annoying. Finally, the starter also evolved, but the strategy didn't need to evolve with it. Use Fearow (Peck) or Kadabra (Confusion) on Ivysaur, Diglett (Dig) on Charmeleon, and Bellsprout/Oddish/Pikachu (Vine Whip/Absorb/Thundershock) on Wartortle.
 * Red and Blue

This strategy is literally the exact same thing as in Cerulean. Use Mankey on the Normals, Ivysaur on Sandshrew, and Pikachu on Fearow.
 * Yellow

Victory!
Once you've defeated your rival, you're free to visit the good Captain and exchange a back rub as a remedy for sea sickness for HM 01, which teaches Cut to just about any Pokémon. As an attack, it's not that great, but when used outside of battle, it lets you cut down those annoying trees that are always blocking your way.

Once you've received HM 01, your quest is complete, and the ship will shove off as soon as you set foot back on dry land. So if you'd like to visit the kitchen or the other decks (to fight the other guests and crew for EXP, cash, and prizes), you might want to save the Captain for last.
