In Baldo The Guardian Owls, you’ll come across The Gokuro Tower dungeon after completing the Rodia Town Owl Tower quest.
Head inside and use your horn on the guardian symbol to unlock the fast travel point here. Light the brazier to the right of the symbol to make it easier to see in this room. Next, climb up the set of stairs on the right side of the screen and use your fire to burn the hanging spider sack.
Go back down the stairs and push the statue to the northwestern side of the room to bridge the gap in the walkway. Walk up those stairs and grab the pumpkin at the end of the path. Bring it to the pressure point in the center of the room to drop a ladder.
If you climb up the ladder and head up the stairs, you’ll notice that the way forward is blocked. You’ll need to exit this dungeon entirely and head to the Owl Museum in Rodia. Push the 2 owl statues into the rays of moonlight coming in through the windows to open a second door upstairs.
Go on up the stairs to the second level and enter the door on the left. Throw an Owl Bomb at the bell to cause the stone to lift from blocking the doorway across the way. Return to the dungeon via the entrance near the library and make your way to the newly opened doorway…
