Catch that pesky wraith !
The Fyxestroll Garden expanse in Honkai : Star Rail house various secret stories told both by the bystander or by those scary Heliobus lying around . One of them concede you the Boo Ha Ha ! Hidden Achievement , and here ’s how you may get this one .
How to Unlock the Boo Ha Ha! Achievement in Honkai: Star Rail
The Boo Ha Ha ! hidden achievement in The Memories We Share section is unlocked by visiting the Little Ghost in all of its appearing areas in order in the Fyxestroll Garden . You probably have already started this side pursuit by accident as you explore the field for the first metre , but there are some big chance you miss some of the meeting . Below are all of the location .
The first encounter will trigger after have the stone lift for the first time after completing the Sojourners ’ Ghastly Reverie Trailblaze Continuation mission ( Guinaifen and Huohuo ’s first seeking ) . Speak with the Little Ghost here and declare to its gift in your inventory .
Now head back to the Space Anchor at the entrance , turn back , and talk with the little smell settle here . It should be betoken with a “ ? ” symbol in its fundamental interaction box .

Now head to the third emplacement next to the Suppression Tower , and a bit of dialogue should be automatically triggered as soon as you draw near the spirits . Get closer to trigger the full event .
Now , keep heading for the next one and speak with the teapot here . Any option is all right and will advance the mini - quest to its final whole step .
Finally , head to the Locufox Forest Backdoor Space Anchor , and you ’ll see the Little Ghost here once again . They ’ll endue you all 900 prizes at once instead of making all of the mean 900 puzzle . Hurray ! What are the prizes , you may ask ? Trash , of course ! I think , it ’s literally Trash . A Pleasant - Looking Trash , to be exact . Oh , but you also unlock the Boo Ha Ha ! accomplishment here , at least .

As I name before , chances are that you ’re already midway through this quest , specially if you had to look for someone who make out about music at an earlier moment , so it wo n’t be a hassle to discharge it after a few more interactions . And an extra accomplishment is always welcome , so enjoy it !
