Find the precise Cat Island family still open after The Rio Grande and collect its own reward.

The island mixes a moving shanty, a balcony Secret, a warehouse-side money chest and a pillar puzzle; completing one does not close the other three.

Why this entry is useful

A four-result diagnostic that uses the live family counter and named unlock to route each unfinished state to one interaction, with a recovery for false completion.

Current Cat Island route leads put the island near 707, 666 and distinguish the tree-stump sheet, manor balcony, warehouse exterior and stela pillar. Exact live markers and inventory names take priority over an old combined coordinate row.

Safe first move

Check Cat Island's current Song Sheets, Secret, Chest and Mayan Stela markers before moving; do not use a completed Rio Grande chase as proof of a cleared island.

Finish line

The Rio Grande, Crimson Sails, warehouse-side chest and Mayan Stone each have their own saved result, while viewpoint and huntable-animal markers are checked only if still visible.

Choose one decision and follow 3 checks in order.

  1. Moving sheetIf Song Sheets is open, approach the live tree-stump paper as The Rio Grande and watch its actual flight. Confirm the named unlock and local 1/1 result before moving to another family.
  2. Stone chainIf a fixed pickup is open, use the manor balcony for Crimson Sails or the chest beside the warehouse for money. The chest counter cannot prove the sails Secret, and the sails unlock cannot prove the chest.
  3. Live mapIf the stela remains, climb its own pillar, align the large circle with the rock to the left, adjust the pattern and collect the Mayan Stone. Keep viewpoint and hunting checks separate from the stone.
Plan it here, then confirm each marker, objective, reward, or counter in your save.

How to use it

Match the marker family before repeating a chase

The Rio Grande is the island's moving Song Sheet; Crimson Sails, the warehouse money chest and the Mayan Stone have different interactions and completion proof.

Recovery path

Cat Island still shows a marker

If Song Sheets reads 1/1, leave the tree stump alone and inspect the open Secret, Chest or Stela family. If the manor balcony is empty, check whether Crimson Sails is already unlocked. If the warehouse chest is open but the Secret remains, go to the balcony; if the stela remains, return to its pillar and collect the revealed stone.

Check the missing family → use its surface → prove the result

  1. If Song Sheets is open, approach the live tree-stump paper as The Rio Grande and watch its actual flight. Confirm the named unlock and local 1/1 result before moving to another family.
  2. If a fixed pickup is open, use the manor balcony for Crimson Sails or the chest beside the warehouse for money. The chest counter cannot prove the sails Secret, and the sails unlock cannot prove the chest.
  3. If the stela remains, climb its own pillar, align the large circle with the rock to the left, adjust the pattern and collect the Mayan Stone. Keep viewpoint and hunting checks separate from the stone.

Counter-first decision

Which family still shows work?

Choose the incomplete family shown in your current save. The Rio Grande's 1/1 Song Sheets result does not close the Secret, Chest, or Mayan Stela family.

Choose the family that is still open in your save; this page will show its next check and proof.

  1. 01

    Song Sheets · tree stump

    Do next

    Approach The Rio Grande at its live tree-stump marker only if the Cat Island Song Sheets family is open. Watch the paper's actual flight and take it when the route permits.

    Open the named sheet route
    Result to check

    The Rio Grande unlocks by name and the island's Song Sheets result reads 1/1 in the current save.

    If this does not match your save

    If 1/1 already appears, do not chase another piece of paper for an open Chest, Secret or Stela. If the paper escapes, recheck its live start rather than assuming a fixed landing path.

  2. 02

    Secret · manor balcony

    Do next

    For an open Secret family, inspect the manor balcony for Crimson Sails. The warehouse money chest is a different interaction even though both are fixed pickups.

    Check the Secret family
    Result to check

    Crimson Sails appears by name in the relevant cosmetic or Secret collection; the money chest state alone is not proof.

    If this does not match your save

    If the balcony pickup is absent, verify whether Crimson Sails is already owned before circling the warehouse. Keep the Secret unresolved if the current build shows a different reward.

  3. 03

    Chest · warehouse exterior

    Do next

    If the Chest family is still open, search beside the warehouse for the ordinary money chest. Do not infer that entering the manor or catching the sheet opened it.

    Target the live chest marker
    Result to check

    The chest opens and the local Chest state changes; neither The Rio Grande nor Crimson Sails substitutes for it.

    If this does not match your save

    If the chest seems open yet the counter remains, filter to the live Chest marker and inspect the warehouse exterior. Do not repeat the stela alignment as a chest fix.

  4. 04

    Mayan Stela · pillar

    Do next

    At the stela's own pillar, align the large circle with the rock on the left, adjust the rest of the white-line pattern, then collect the revealed stone.

    Review the stone chain
    Result to check

    The Mayan Stone pickup and stela state change. A synced viewpoint or completed song sheet cannot prove this puzzle result.

    If this does not match your save

    If the pattern will not register, reposition at the active pillar and change camera/scale in the current puzzle. If it registers but the marker remains, check the revealed pickup before leaving.

Before you leaveRead the local family counters one more time. The viewpoint and Howler Monkey are separate island checks if their markers are still open; neither changes the named sails, sheet, chest or stone proof.

Route Plan

Check the missing family → use its surface → prove the result

Catching The Rio Grande on Cat Island's tree stump solves only its Song Sheets family. The manor balcony has Crimson Sails, the warehouse exterior has a money chest, and the Mayan Stela needs a separate circle-alignment and stone pickup. Use the unfinished family, not the island name alone, to choose your return.

  1. Use 707, 666 as Cat Island's area anchor, then filter the current map to the still-open family. A 1/1 Song Sheets result means you should not repeat The Rio Grande chase for a different marker.
  2. For fixed pickups, check the manor balcony for Crimson Sails and the chest beside the warehouse for money; verify the sails by name instead of treating the money chest as its proof.
  3. For the Mayan Stela, use its own pillar, align the large circle with the left rock and adjust the pattern scale; collect and verify the revealed stone separately from the viewpoint and hunting marker.

Use the unfinished family as the compass

Use the unfinished family as the compass

Cat Island's four featured outcomes are different interaction types. A single route line would hide the reason a 1/1 song result can coexist with another open marker.

  • Song Sheets open: use the tree-stump start and named Rio Grande unlock, not the manor or warehouse.
  • Secret open: inspect the manor balcony and Crimson Sails by name; Chest open: inspect the ordinary money chest beside the warehouse.
  • Stela open: solve the pillar alignment and collect the Mayan Stone; checking the viewpoint alone will not close it.

Stop repeating the wrong pickup

Stop repeating the wrong pickup

When one marker remains, preserve the results already present in your save and retry only the corresponding interaction.

  • A 1/1 Song Sheets state is a reason to stop retracing The Rio Grande's flight.
  • A money chest does not award the manor's Crimson Sails, and the sails do not increment the ordinary chest family.
  • If the stela appears solved but the island still flags it, check the revealed stone pickup before realigning the pattern.

Common Questions

Why is Cat Island not clear after The Rio Grande?

The Rio Grande is only the moving Song Sheet. Check the remaining family: Crimson Sails is on the manor balcony, an ordinary money chest is beside the warehouse, and the Mayan Stone needs its own pillar puzzle. A 1/1 Song Sheets result does not close these other markers.

Are Crimson Sails in Cat Island's warehouse chest?

No. Crimson Sails is the manor-balcony Secret, while an ordinary money chest sits next to the warehouse. Verify the sails by name and confirm that the chest opened in your save.

How do I finish Cat Island's Mayan Stela?

At the stela pillar, align the large circle with the rock on the left and scale the remaining pattern to fit. Collect the revealed Mayan Stone, then verify its stela state rather than using the viewpoint or Song Sheets counter as proof.
