Pokémon Legends: Arceus, out today, is set in an earlier version of Pokémon Diamond and Pearl’s Sinnoh region called Hisui. Of course, it’s packed with tons of little Easter eggs and nods to Diamond and Pearl locations and characters. But a special clue tied to a Legendary Pokémon encounter is a mystery that can only be solved if you know about an Easter egg in Brilliant Diamond/Shining Pearl.
Warning: Spoilers for Pokemon Legends: Arceus’ new Pokemon, Legendary Pokemon, and side quests follow. Read at your own risk!
In the second act of Pokémon Legends: Arceus, Professor Laventon gives you a side quest called “The Legend of the Sea”. He mentions a mysterious Pokemon he saw out on the ocean and suggests you might find it in the Cobalt Shorelands. But beyond that, there’s absolutely no detail on how to encounter it or what Pokemon it is in the first place, and just wandering the Cobalt Coastlands won’t get you anywhere. But if you’ve played Brilliant Diamond/Shining Pearl and remember a specific text in the Canalave library, you might be able to solve this puzzle.
You see, “The Sea’s Legend” is also the name of a book you can read at this library that goes something like this:
Once upon a time in the Baltic Sea there was a Pokémon known as the Prince. A brave human asked sea-dwelling Pokémon to show them the prince. Mantyke, Buizel, and a quilfish with huge spikes recognized the human’s courage and joined them. Together they rode in a boat across the sunset-streaked sea and sailed through the ocean gate that stretched above the waves. News of this reached the ears of the prince, who wished to meet the brave little company at Seaside Hollow.
If you follow these instructions, you can find the Princely Pokemon. You need a party with Mantyke and Buizel, as well as Quilfish’s brand new evolution, Overquill. With them in your team, wait until the evening and then sail on Basculegion from the camp on the coast through the giant pillars sticking out of the water in the ocean. You should get a message saying a rock has moved. If you do, you can then sail to Seaside Hollow, a cave in the ocean on the other side of the cape to find Manaphy accompanied by two Phiones. If it doesn’t work, check out our full guide on this side quest, including how to acquire Overquill.

While this whole quest chain is small, it’s an interesting connection between the two games, especially since the information Laventon gives you doesn’t tell the whole story of what you need to do to find Manaphy. There are also other benefits of having played Brilliant Diamond and Shining Pearl, as the saved data will trigger a search for another legendary player on your system. Pokémon Sword and Shield save dates will trigger a similar but different legendary quest.
We reviewed Pokémon Legends: Arceus and found its overhauled systems to be absolutely revolutionary for the Pokémon franchise, but we were disappointed with the empty, semi-open world it was set in. With its release, we’ve got tons of guides to help you on your Pokemon journey, and you can find them all here.
