The Mailroom · Story walkthrough
Follow Days 1–5: get your tools, hide the frog, repair the compressor and prepare the items needed to escape.
Day 1 — the frog is not a knife puzzle
Show story spoilers
Clock in, answer the intercom and finish the mail tutorial. Send the frog from the marked canister through tube 2; its pictogram shows the destination. Continue sorting until the final box arrives. Open it and PICK UP the note asking you to process the frog: taking that note triggers the end-of-day sequence. There is no knife to collect yet. Wait for the message at the time clock, collect your pay, clock out and take the elevator.

Day 2 — restore the compressor
Show story spoilers
Go to the machine room. The wrench lies on the floor beside the cabinet with bottles. Pick it up, aim at each of the two damaged pressure bolts and hold Repair with wrench until each is repaired. Then operate the compressor's large lever. If it still refuses to start, inspect both bolts and the blood tank; the machine needs all of them healthy. Return to the sorting table once the tubes work.
Day 2 — open the mortar crate
Show story spoilers
The first delivery supplies the knife. Shortly afterwards a crate containing the mortar and a crowbar arrive at the table. Pick up the crowbar, aim it at the crate and complete Open with crowbar. Move the mortar onto the table. Complete the recipe orders and read the assistant's help note. Keep the knife and mortar available for later days.
Day 2 — hide the frog
Show story spoilers
After completing the final delivery batch, the assistant points you toward the Employee of the Month portrait. Open that portrait as a door, pick up the frog and put it inside the recess behind it. Close the portrait with the frog fully inside. Closing an empty recess will not advance the event. The search scene then plays; wait for control to return and finish the shift.

Day 3 — open the security office
Show story spoilers
Read the updated directory before sorting. The second delivery brings the security key. Carry it to the locked security-office door and use Unlock. Inside, approach and look directly at the Pepe Silvia board. Letters bearing that name can be taken into the office to remove them from the current workload, or burned as junk. The three office bins initially contain 45 extra Pepe letters.
Day 3 — refill the blood tank
Show story spoilers
When the compressor runs out of blood, take an empty bottle and the mortar. Blood fungus grows beside the sorting table and in the machine room; a loose piece also sits on the small machine-room table. Harvest it and grind it into blood. One whole piece yields up to 250 mL, so grind two for the empty 500 mL tank. Pour the blood into the compressor tank until its level reaches 100%, then pull the lever to restart. Other liquids do not refill this tank.
Day 3 — collect the diamond
Show story spoilers
Complete the last mail batch to trigger the frog's return from the tube. After the conversation, payment and a diamond fall from the money chute above the sorting area. Pick up the diamond so its counter increases. It is needed for the soul gem later; leaving it on the floor is not the same as collecting it.

Day 4 — scales and the assistant's secret
Show story spoilers
The spellbook is on its pedestal. Read the furnace page and hold Cast spell to light the furnace for longer. After the second delivery, open the new crate with the crowbar to obtain the scale. Use it for the meat orders. Ringing for the third batch triggers the assistant's revelation and unlocks the soul-gem spell. Finish the remaining work, collect the diamond in the end-of-day payment and clock out.

Day 5 — finish work before the sacrifice
Show story spoilers
The day begins in low gravity; read the spellbook's gravity page and cast it to toggle the effect if moving items is awkward. Check the directory again and complete all three delivery batches, including the meat and potion orders. The final batch triggers the frog's sacrifice conversation. Wait until it ends and the heart checklist appears before using the knife on the frog.
