How do swimming and diving work in River King 2?

Buy Flippers, equip them, enter deep water to swim, then dive on seafloor spots for shellfish. You cannot dive without Flippers equipped.

Where do I get Flippers?

Buy Flippers at the Beach Tackle Shop. Teen players do this after the Beach Canoe step; Kid players buy them after reaching Beach through the home hub.

Where is Pearl Oyster?

Dive in the northeast Beach water for P.Oyster (Pearl Oyster). On the Teen route, deliver it to Dad on the south side of Shore to open the boat route.

How many shellfish are in the Shellfish Memo?

There are 24 shellfish entries: about 6 at Beach, 9 at Shore, 7 at Ocean, and 2 at Remote Island.

What are Scallops used for?

Two Scallops open the mermaid shipwreck clue on Ocean for the Heaven Jewel / Shore island path. Keep them until that exchange is done.

Q: How do I reach the underwater palace?

Pay 300G to release the Turtle at Beach, then meet the Turtle east of the Shore dock and dive for the princess route.

Flippers turn deep Beach, Shore, Ocean, and Remote Island water into swimming lanes. Dive for shellfish, open Dad's boat with Pearl Oyster on the Teen route, then chase Turtle, Scallops, and the full Shellfish Memo.

Quick answer

How swimming and diving work

1
Buy Flippers at the Beach Tackle Shop.
2
Equip them from inventory before you enter deep water.
3
Swim into coastal deep water, then dive on seafloor spots.
4
Teen only: grab Pearl Oyster (P.Oyster) in northeast Beach water and give it to Dad at Shore.
5
Keep story shells until the trade finishes—especially Pearl Oyster and Scallops.

Without Flippers equipped, deep water is a wall. With them, shellfish fill the Shellfish Memo the same way fish fill the Fishing Memo.

Building dive plan…

Step by step

From Flippers to first shellfish

The loop is short: shop → equip → swim → dive → memo.

1

Reach Beach and the Tackle Shop

Teen starts at Beach. Kid reaches Beach through the home hub after Lake progress. The Dive guide near the shop reminds you to buy Flippers before the six Beach shellfish spots.
2

Buy and equip Flippers

Purchase Flippers (in-game item name: Flippers) at the Beach Tackle Shop, then equip them. An unequipped pair does nothing in the water.
3

Enter deep water and dive

Walk into deep coastal water to swim. Dive on seafloor collection spots to pick shellfish. Surface when your air or path runs out, then dive again on the next spot.
4

Log the Shellfish Memo

New species register on the Shellfish Memo (24 entries). Duplicates can still matter for trades—Pearl Oyster and Scallops are the main story shells.

Route differences

Teen boat gate vs Kid coastal access

Both routes use the same Flippers and shellfish tables. Only early access timing and the Pearl Oyster boat story differ.

Teen route · required story dive

Flippers + Pearl Oyster open Dad's boat

Finish the Dandelion → Canoe exchange at Beach so you can cross water cleanly.
Buy Flippers at the Beach Tackle Shop.
Dive northeast Beach water for Pearl Oyster (in-game: P.Oyster).
Talk to Dad on the south side of Shore and hand over the oyster.
Use Dad's boat for the Ocean dock and later cruiser travel.

Do not sell the first Pearl Oyster. Without this hand-in, Shore boat access stays closed even if you can walk the Beach–Shore path.

Kid route · later coastal diving

Unlock Beach, then dive for completion

Clear early Lake gates (Canoe, Watch, Pink → Stream) through the normal walkthrough.
Travel through the home hub to Beach when that coast opens.
Buy Flippers at the Beach Tackle Shop the same way Teen does.
Dive Beach, Shore, Ocean, and Remote Island spots for the Shellfish Memo.
Treat Scallops and other trade shells as quest items until the NPC takes them.

Kid players still need Flippers for shellfish completion. The Pearl Oyster → Dad boat sequence is the Teen story gate; Kid coastal timing follows the Lake-first walkthrough.

Common swimming problems

I cannot enter the water at all

Buy Flippers and equip them. Deep water blocks you until Flippers are on—owning them in the bag is not enough.

I can swim but find no shellfish

Look for seafloor dive spots, not every open tile. Beach has six shellfish locations; the Dive guide near the Tackle Shop points you at that early loop.

Dad will not give me the boat

Teen route only: dive northeast Beach for Pearl Oyster (P.Oyster), keep it, and talk to Dad on the south side of Shore. Walking the Beach–Shore path does not replace that hand-in.

I cannot find the Turtle underwater palace

Pay 300G to the Turtle boy at Beach first, then search east of the Shore dock for the Turtle and dive from there.

Mermaids will not help at the shipwreck

Bring two Scallops from Ocean diving. That opens the old-man clue for the Shore island / Heaven Jewel path.

Quick reference

Swimming & diving FAQ

Do Kid and Teen use the same Flippers?

Yes. Both routes buy Flippers at the Beach Tackle Shop. Teen needs them earlier for Pearl Oyster; Kid buys them when Beach opens.

Is Pearl Oyster only for Teen?

The Dad boat hand-in is the Teen Shore gate. Pearl Oyster still counts as a Shellfish Memo entry for both routes.

How many shellfish are there?

24 on the Shellfish Memo: roughly 6 Beach, 9 Shore, 7 Ocean, and 2 Remote Island.

What is the Net for?

A general water Net item supports collection loops alongside Flippers. Flippers are the required swim-and-dive unlock; keep inventory space for shells and quest trades.

Can I track shellfish on my cartridge from this page?

No. The checklist stores progress only in this browser. Your real memo still lives on the Game Boy Color save.

Where next after the first dive?

Open the Walkthrough for Shore and Ocean story order, or the Sea & River King guide once boat travel is unlocked.
