despite how old my account is, i never got around to unlocking the blue building and im looking at what is needed for it now. One I saw is make a hundred posts. Another is I need 250 achievements done, so im here to ask what do you think the easiest one to get are? I really want to get a bumbus :3

There are a number of tasks required for the Blue Building. This guide is on the Subeta Wiki -

https://subeta.fandom.com/wiki/Blue_Building I can't remember how you get a password now - it might be by going to the Blue Building and refreshing. I don't think you have to write it down but I got in there about 19 years ago so my memory is a bit hazy.

If you go to the Blue Building on the Centropolis map it should tell you what tasks, if any, you have already achieved.

Just confirming that you get the password from refreshing the building page and you don't need to write it. I got mine ~6 months ago that way by hard refreshing, I never even saw the event.

I see you already have 246 achievements, so you're almost there! You might already have some, but they need to be activated. Like checking your sticker album or your wardrobe, or your main pet's books read or foods eaten to see if you have all of them activated already. Lifelike doll achievements are relatively easy to get, most of the older ones are not that expensive.

thank you for the help
