Owlboy Achievements Guide: Missable Trophies, Secret Items, and Post-Game Content

A practical Owlboy achievements guide covering Bad Boy, Hot Spring Mastery, the 1,000-hit Oops trophy, the hidden bongo-house key, and the post-game Eternal Owl Sanctuary.

Owlboy Achievements at a Glance

Most Owlboy achievements unlock automatically as you guide Otus through the story, so the real challenge for completionists comes down to three trophies that are easy to miss or that require deliberate effort: Bad Boy, Hot Spring Mastery, and Oops. Beyond the trophy list, the game also hides post-game content and secret items that round out a true 100 percent run.

AchievementHow to Unlock ItWhen It Is Available
Bad BoyDrop Geddy the instant you receive himFirst minutes of a new game
Hot Spring MasterySoak in the hot spring during the early Vellie sceneEarly game, very easy to miss
OopsHit Geddy 1,000 timesAny time Geddy is your equipped gunner

The two early-game trophies are the reason many players end up restarting: if you blew past those scenes on your first save file, you need a fresh playthrough to trigger them. For a complete visual walkthrough of the endgame, the bonus episode "SECRET AREAS and ALL ACHIEVEMENTS" from Mo Monocle is the most thorough video reference currently available.

How to Earn Bad Boy, Hot Spring Mastery, and Oops

  • Bad Boy: Start a new game and, the moment Otus gains Geddy as a gunner, drop him immediately. The achievement pops on the spot, exactly as demonstrated in the source video.
  • Hot Spring Mastery: Early in the game you are directed to the hot spring in the Vellie. Talk to the elder, Toby, follow his advice, and complete the short soaking scene to earn the trophy.
  • Oops: Equip Geddy and hit him 1,000 times. According to the video, a large portion of the counter accumulates naturally during a normal playthrough, so the dedicated grind only took roughly 20 to 25 minutes of continuous strikes to finish.

How to Open the Post-Game Owl Sanctuary

After the credits, Owlboy keeps a major secret area behind a medallion you found in the Owl Tower. Follow these steps:

  1. Return to the tower area at the end of the game and activate the glinting spot tied to the medallion.
  2. Travel up through Strato toward the plateau with the floating, Metroid-like enemies. Bring Twig along; his shots make the trip far easier.
  3. Place the medallion in its recessed slot. Nothing happens at first, but the previously sealed door nearby unlocks, connecting two areas that were once part of a single structure.
  4. Head through the new door to reach the Eternal Owl Sanctuary, the game's primary post-game zone. Explore every corridor, examine each owl statue, and grab the fruit scattered around the halls.

On the way, take a moment at the small white tree near the entrance. Earlier in the story Otus reacts sadly there, but after the ending he no longer does, which is why fans speculate the tree marks a grave.

Secret Items: The Bongo-House Key and the Chest Behind Twig's House

One secret is nearly impossible to find without help, and even the video's creator admits he had to look it up. Here is the sequence:

  1. After fully exploring the sanctuary, check the uncollected item near the conch shell. Its clue points you to the bongo player's house.
  2. Visit the bongo player's house and speak with everyone inside, including the residents hiding out there.
  3. Play the drum puzzle in this order: Left, Right, Right, Right, Left, Right. Solving it awards a key whose description notes it would not open any door in the Vellie.
  4. Take that key to the small vent behind Twig's house in Mesos, the spot that only displays a question mark when examined.
  5. Open the chest inside. It holds sheet music, old drawings, trinkets, and a heartbreaking note from the surviving brother who left for somewhere warmer, carrying both sets of drums so the songs would not be forgotten.

The scene is one of the quietest, saddest moments in the game, and the item's deliberately mundane description makes it easy to overlook entirely.

Spoilers: What the Eternal Sanctuary Reveals

Skip this section if you have not finished the story. The sanctuary holograms fill in the largest remaining lore gaps:

  • Sarnia of the House of Preservation and Diplomacy introduces the Eternal Sanctuary as a record of the brightest owls who ever lived.
  • Recordings describe pairs of brilliant ancients, including the temple guardians and an inseparable duo whose revolutionary automatons changed owl society forever.
  • The mathematician owl, rendered as "Nokton" in the video's captions, designed the Hex machine that sustains the loop. His partner completed it in secret after his death, calculating 50-50 odds of catastrophe, and hid a confession plus a backup plan behind crest-marked doors, which strongly implies how Solus knew what to do.
  • The final message is addressed directly to Otus. Its speaker predicted his own death "again and again in an infinity," foresaw Otus falling in a great battle above a floating city, and notes that Otus standing before the recording proves the loop worked after all.

Frequently Asked Questions

Are any Owlboy achievements missable?

Yes. Bad Boy and Hot Spring Mastery only trigger during the opening stretch of the game, so players who rush the story must start a new save. Story-related trophies, by contrast, unlock automatically as you progress.

How long does the Oops achievement take?

You must hit Geddy 1,000 times. Because accidental strikes count toward the total across your whole playthrough, the source video's creator only needed about 20 to 25 minutes of deliberate grinding to finish the count.

Do I need a new game file to finish the owlboy achievements list?

Only if you missed the two early-game trophies. Return to the title screen, select New Game, and trigger Bad Boy and Hot Spring Mastery within the first few minutes of play.

Where do I use the key from the bongo house?

Take it to the small vent behind Twig's house in Mesos, the examine spot that previously only showed a question mark. It opens the hidden chest containing the sheet music and the brother's farewell note.

Is the Owl Sanctuary required for full completion?

It is not tied to the three combat trophies, but it is essential for players chasing 100 percent exploration. It houses the game's final collectibles, hidden fruit, and the closing lore revelations about the loop and the ancient owls.
