Chapter 4 – Underground Blossom Walkthrough
At Bird Bridge Station, you’re met with another set of strange encounters and puzzles to solve before earning your ticket to the next stop. A new character has just completed a sketch, interact with her to begin.
Open the nearby box to collect a pencil and a piece of sausage. Give the pencil to Laura so she can sketch a line on Rose’s face; take the line and add it to your inventory.
Move to the next room and open the sewer cover to grab a stick. Combine it with the line to create a makeshift fishing rod. Head further right to find a poster of a singing woman, press her mouth and observe the music notes. Then go to the man with the trumpet and play the notes in this order: 1, 2, 3, 1, 2, 3. A fish will fly out of the trampoline, leaving behind a hook.
Go back to the sewer and attach the hook to your rod. Add the sausage as bait, then lower it to fish out a rat. Follow the rat to the fourth room and read the note it drops at the crevice, it mentions a specific time.
Head to the third room, find the clock, and set it to 5:00. A train arrives and drops off a few passengers asking about a man in a red hat. Track him down in the second room and speak to him, he’ll direct you to his colleague with a brown suitcase. Check that man’s pocket to get a pair of glasses and a clue that the man with the hard hat needs them.
Find the man in the yellow hard hat, give him the glasses, and he’ll mention the “tall smiling man.” You’ll find him back at the station, check his pocket to get a tie. Now, look for a man without a tie in the Bird Bridge Station room and give it to him. He’ll then ask you to find a man wearing a green tie.
Go to the food and drink shop to find the green-tie man. He tells you, “You’re confusing me with my twin brother,” deepening the mystery.
Next, enter the room with the “Rusty Lake Theatre” poster. Interact with the three men and click the middle one to get a lighter, though he tells you, “You’re talking to the wrong person.”
Head back to the man who asked for coffee earlier. Speak with him and receive money. Visit the shop and buy a coffee and sandwich. Give the coffee to Laura and inspect the cup to find a cigarette. Then give the sandwich to the man, drag off the worms first, and he’ll leave behind breadcrumbs.
Back at the food shop, give the cigarette and lighter to the suspicious man hiding behind the counter. He’ll rob you but leave behind a paperclip in an apology note. Use this to unlock the electricity box near the bench.
Solve the circuit by connecting wires in this order: 1 to 9, 2 to 4, and 3 to 7.
Now revisit the speaker above Laura to hear a tune. Return to the trumpet and replicate it by playing: 1, 1, 2, 2, 3, 3. A bird is released and flies to Laura. Feed it the breadcrumbs and listen to the tune it sings.
Go back to the trumpet player and reproduce the new tune: 3, 3, 1, 3, 1, 1. A hand appears, giving you the metro ticket.
Before leaving, check Laura’s sketchbook near the bench and flip to the last page. It reveals the time 3:45. Set the station clock accordingly, show your ticket to the conductor, and board the train to your next destination.
What’s the final trumpet tune to get the ticket?
After feeding the bird, repeat the new tune: 3, 3, 1, 3, 1, 1 — the hand will give you the metro ticket.
What’s the circuit box solution with the paperclip?
Connect the wires as follows: 1 → 9, 2 → 4, 3 → 7.
