Pokémon HGSS: Bill’s Grandfather Side-Quest Guide + Rewards List

Standing at Bills Grandfather's Sea Cottage on Route 25 (Pokémon HeartGold)

In Pokémon HeartGold and SoulSilver, Bill’s grandfather will give you five Evolution stones if you show him a series of five Pokémon. You have to show him each Pokémon in a specific order, and you can only get each stone one time.

Bill’s grandfather can be found housesitting for Bill at the Sea Cottage on Route 25, located just north of Cerulean City.

In this guide we’ll cover exactly which Pokémon you need to show him, where to find those Pokémon, and which stones you’ll get for all your hard work.

Where To Find Bill’s Grandfather

Inside the Sea Cottage on Route 25

Bill’s grandfather is located in Bill’s old house from the original Gen I games. This is the Sea Cottage on Route 25 in Kanto, directly northeast of Cerulean City.

So you’ll need to go all the way up Nugget Bridge and walk to the end of Route 25.

But before any of this, you’ll first need to beat the Elite Four in Johto and make your way through Kanto to reach Cerulean City.

Pokémon List for Bill’s Grandfather

Once you’ve spoken to Bill’s grandfather, he’ll ask to see a certain Pokémon.

He won’t tell you exactly which Pokémon, but he will give you clues. If you bring him the correct Pokémon, he’ll present you with an Evolution Stone and request to see another.

Note: Some of Bill’s grandfather’s requests will be different depending on which version of the game you’re playing. His requests also don’t follow a particular order, so he might ask for a Pichu first, and then an Oddish.

There are a total of five stones that you can earn this way:

And here’s a full list of the Pokémon you’ll need to catch for each stone:
