Here's my thoughts on all the clues! My final total was 19/25.
Egg 1 - Found this one in no-time; I knew it was the April Fool's joke.
Egg 2 - I like to spin my umbrellas, so I thought of the answer to this one straightaway.
Egg 3 - This one took me a minute! I'm not super familiar with Sanrio, so I did some searches for "Puroland", thinking it was maybe in someone's airport thread, but when I learned that Puroland was a Sanrio theme park, I knew it had to be in the official AC x Sanrio thread.
Egg 4 - I don't use Discord much so this didn't come to me immediately, but I had a feeling that "chaotic chatter" was refering to The Basement. I looked through the Discord/Chat Group directory for a bit, but then noticed the link to the Bell Tree's official Discord, and found it there!
Egg 5 - As much as I play Quick, Before the Mods!, I'm a little embarrassed by how long this took me. OTL I was trying to figure out what a "code 577" was, thought #ABB,BAD was a hex code, looked at the staff pages... and then the phrase "incubation unit" hit me like a ton of bricks. I actually remembered the page number because I'd gone back to that post a couple times to double-check the new rules, so it didn't take me long to find it once I realized.
Egg 6 - I was so convinced this had to do with Brewster's, until I finally remembered the whole "buy me a coffee" thing on Ko-Fi, and then I knew it was something to do with the Bell Tree Ko-Fi page.
Egg 7 - First I checked the New Horizons one year anniversary post, but I soon realized the second line was probably about resetting one's island.
Egg 8 - Never found this one; I never thought to click the mark read button. ;; I checked the Blog Tree Archives, locked threads in Island Journals (read through all of dizzy bone's island journal thinking it would be there, lovely island though!), practically all the locked threads in the Bulletin Board (thought for sure it was going to be in one of The Woods threads), locked threads in the New Leaf section... I learned a lot about the site at least.
Egg 9 - Knew where this one was right away, thanks to my research from #8.
Egg 10 - Same with this one! #8 saved me again.
Egg 11 - I knew about the vitamins thread, so this one was easy too.
Egg 12 - I was really focused on the "flaming camelid" part, and despite how much digital art I do, I didn't know about FireAlpaca! I thought about the Firefox browser but didn't think that could be it (because foxes are definitely not camelids ahaha), then I looked for Saharah, then switched to looking through Pokemon threads for Numel and Camerupt. At this point I decided to quit focusing on that part of the clue, and guessed that "expressing yourself via electronic apparatus" was probably about digital art, so I went to the Museum forum and checked out the list of art programs. Then I saw FireAlpaca right at the top of the post and was like "OH"
Egg 13 - Knew this was about dream addresses!
Egg 14 - First I looked if it was in a Teenage Mutant Ninja Turtles thread, then I googled what Donatello's weapon was because I never watched the show ahaha. I got really stuck on "bo" and thought maybe it was referring to Beau? And then when I saw "Contact the Staff" in the forum list, it hit me. I was still pretty hesitant to post there despite the "Posted!" part of the clue, so I checked Ask the Staff and the Information Desk before finally going for it and posting a thread there.
Egg 15 - Thankfully, I remembered Halloweaster before I went down the weird folklore rabbithole.
Egg 16 - Was looking all over the place for stuff relating to Blathers and Celeste, checking the Museum threads, and finally decided to look in "What are you reading?" on a wild guess. I... didn't think I was actually going to find it there.
Egg 17 - I looked all in Nook's Cranny but never found pandapple's thread, though I did check the post by dizzy bone. ;; Also checked the Official Blue's Clue's Fan Club Megathread and was super disappointed it wasn't there. I even looked in threads about colors and music, but alas.
Egg 18 - I think I was tired by this point because I got really stuck on the house collectible restocks. Finally figured out it was Sanrio though!
Egg 19 - Checked so many threads about Dodo codes, never thought to try and post one.
Egg 20 - I thought this was about one of the doll collectibles, or Zipper T. Bunny.
Egg 21 - Knew it had to be in the Egg Decorating thread and clicked the Goose egg picture first thing!
Egg 22 - I found some old voting threads with Pietro and thought it would be there, but I eventually clicked the link in the Sanrio poll and found it.
Egg 23 - Had no idea about the Museum Day thread, so I kept checking Bell Fair closing ceremonies.
Egg 24 - Thought this was about signatures for a minute, but quickly realized it was actually lineup!
Egg 25 - Looked in the What's Bothering You and What Are You Happy About Today threads, but I didn't search super hard for this one because I was ready to call it a hunt at this point.
Anyways, big thanks to the staff for all the work put into the Easter event! ^^ I had a lot of fun, got a good workout for my brain, and came out of it with a lovely Dragonscale egg. Although, "egg" has stopped looking like a real word to me.
