Hidden Treasures & Secrets: Sunken Ship Part 2

After defeating King Calamari, use the spring to return to the boss room, then proceed northeast.

In the next two-story room, you will encounter a Dead Bones enemy. Ignore it and go through the northeast door to the lower part of a room where Alley Rats fire Bullets from cannons.

To make dodging easier, you can jump and hit some of the northeastern bullets as they fly overhead from the crates, preventing further shots from that cannon.

Return to the Dead Bones room, jump on the corner crate, then jump to a higher ledge and through the northeast door to reach the upper part of the cannon room.

Dodge the bullets or jump over the cannons. Attacking the Alley Rats on the cannons will not stop the bullets, but jumping over the cannons prevents them from knocking you down.

Exit the cannon room to the southeast.

In the next area, you will find a staircase with patrolling Alley Rats. Go through the door at the bottom of the stairs into a larger room with Alley Rats and Dead Bones.

Two chests are located atop a pile of crates. To reach them, jump onto the barrels in the northern corner, then jump southeast onto the crates. These chests contain Coins.

Exit through the northwest door to find a clone of Mario (Clone Mario or Mirror Mario) that mimics your actions in reverse.

If you have the Signal Ring equipped, you will detect a hidden treasure. Head southwest towards your clone and jump around the middle of the room, near the southeastern wall, to find a hidden J-box.

Hitting this J-box reveals a hidden treasure to the northwest, high above. Stand on Clone Mario’s head to reach it. Head to the northwestern wall, directly under the hidden treasure, and jump onto Clone Mario’s head by running into the wall and jumping, then turning southwest in midair. Jump up to hit the hidden treasure chest and obtain a Croaka Cola.

Exit the clone room via the southwestern door, returning to the previous room on the other side of a crate wall.

Exit southwest to a new room with three Dry Bones patrolling. A fight here may involve 2x Greapers, 2x Dry Bones, and 1x Reacher. A Mallow with Thunderbolt can defeat them efficiently. This fight offers good experience and Coins.

Go to the northern corner of the room and behind a wall of J-boxes. You may need to fight a Dry Bones. Search the northwestern wall for a door leading to a treasure room.

Hit the chest inside to obtain a Frog Coin. Exit back to the room with the three Dry Bones and take the stairs down to the southwest.

You will find a Save Point. Jump over a crate wall near the Save Point and hit a chest to obtain a Mushroom.

Use the Save Point, then vault over a second crate wall to find another chest. This chest is a Whuhoh (Mimic) in disguise.

The Whuhoh is weak to jump damage; a perfect Super Jump can deal over 500 damage. Use Thought Peek to examine it and the Mini Goombas it summons.

Defeating the Whuhoh earns you the Safety Badge accessory, which prevents Poison, Scarecrow, and Sleep debuffs.

Swim into a whirlpool to go underwater and collect more Frog Coins.
