If you find any more, let me know and I'll add them!
General - Aira is left-handed while Tidus is ambidextrous. The following characters seem to be right-handed: Azari, Sophie, Cronan, and Naida.
Season 1[]
Crushing It - The girls' forehead designs aren't tattoos, they're removable crown accessories! You can see in webisode 1 that Aira takes hers off!
Elves Got Talent - The music at the very beginning is actually coming from Farran, who is playing what looks to be a tin whistle.
Never Cave - Why does Naida have an entire barrel full of doughnuts?!?!?!?
Season 2[]
General - Azari's season 2 shoulder marking matches the symbol on Ragana's Change From Within dress.
I assume the two elves that the cookie-snatcher is always next to are her parents! Her colouring even looks like a combination of the two.
Another detail that caught my attention is that the guy is holding an earth flag. So either he's an earth elf despite his blue colouring, or he's just being supportive of his wife/girlfriend and daughter's elements, which is so sweet!
The guy has the same star-shaped leaf on his trunk that the lady has on her dress. Also, the longer-haired guy next to him has the earth symbol on his trunk. I wonder if he's part of the family too. Cookie-snatcher's uncle???
The white-haired background guy wore glasses during the Dragon Race but not at the Market Place.
Dragons to Save, Time to be Brave - There is a guitar in Emily's room, and she has pictures of her 4 elf friends above her bed. Also, there is a stick on Emily's desk that looks like the one the elves gave her for Christmas (aww, she kept it!) Later on, we see a blackboard in Tidus' school showing that it's not okay for dragons to eat people, but they're allowed to eat cookies. (Cory needs to enroll at Tidus' school, ASAP!)
MyanCatRocks noticed that there's a globe with at least 5 continents on it at the elementary school. This means that the world of Elvendale is likely a spherical planet, similar to Earth. There's also another globe at the dragon school.
The most startling thing I've ever encountered is probably that AZARI ISN'T IN THE DRAGONS TO SAVE FLASHBACK. Now, I could be overreacting here because maybe she was just sick that day and missed school. HOWEVER. We have to consider the alternative possibility. What if Azari was the last elf to join the group??? Maybe she hadn't met them yet!!! 😱
Based on Aira's reaction in Another Kind of Magic, I initially thought that binoculars didn't exist in Elvendale. But they do! Sira has a pair (and so does Naida.) There are also telescopes everywhere, which work similarly.
Down a Dark Path - These two elves look like they could be the present-day versions of Ragana's bullies! It's kind of nice to think they stuck together all this time, even if they were sort of awful as kids. They're lucky Ragana was so focused on the main 5, or else she might have recognized them!
Safety First - In webisode 6, we see that Naida can make rainbows! And apparently, she can store rainbows in her bag? I don't know how that works, but that's pretty cool!
We all know that Azari is homeless, but then where does she keep her clothes and belongings? They must be inside that green trunk. I can't help but wonder though why she lugs a birdcage around with her when she doesn't even have a bird. Maybe she did at one point, and she keeps it for sentimental reasons? Could it have been a phoenix?
Drag Race - The tips of the dragon's tails are all designed differently to match their elements. Merina has fins, Thorne has crystals, Zonya has flames, and Gust has feathers.
Rumor Has It - Tidus is playing cards in webisode 9. Instead of hearts, diamonds, spades, and clubs, Elvendale cards have the four elemental symbols! Also, at the very beginning, the main 5 each have a different straw that matches their elements and colour schemes. (I've also included Sira's straw from Down a Dark Path.)
Born To Do It - Nothing major, but I thought it was cute how Miss Spry is using Farran's boot as a chair.
One is More Fun - There's a picture beside Ragana's mirror of Tidus . . . and there's a lipstick mark on it! Also, the water in Ragana's sink is green and the faucet is shaped like the Shadow Fountain. (Noticed by SavagexxFox) In Evil Apprentice, we can even see green water leaking out from the base of the castle.
Change From Within - Towards the end, the townspeople chase after Ragana and she hides in the bushes. Either this guy has a twin brother or there's some freaky voodoo teleportation going on here because he runs past TWICE! If you watch it really slowly, you'll see he's the first runner and the sixth runner in line.
That is one intricate and intriguing symbol on the market stall canopy. I'm also curious as to what the pink dust being sold there actually is.
While all the other townsfolk are fawning over Ragana, yellow-haired guy in the back there is just completely unamused, dare I say miffed. (Was he HOPING for the rock to crush someone!?)
Season 3[]
Welcome to Elvendale - The stickers from the sets give us a few clues about how much certain things cost. (Cupcake - 2 leaves. Croissant - 1 leaf.) But webisode 19 is particularly fascinating to me. An acorn is more expensive than an apple, but that might be because Mr. Spry is a squirrel, and therefore sees acorns as being more valuable. If this is true, then does that mean a bunny vendor could increase the price of carrots? Could a mouse vendor increase the price of cheese? It's a peculiar concept! And what do the leaves actually mean???
Evil Apprentice - There's a skeleton in Ragana's dungeons . . . which means she killed someone! But that's not the first skeleton we've seen in connection to Ragana. There's another one in the tunnels under her castle. This victim was fatally wounded by arrows in the chest. (I guess Rosalyn's not the only one going around shooting people in the heart.)
SavagexxFox noticed that the skeleton in the mines has two large fangs sticking out from the lower jaw. Could the skeleton belong to a troll? It has the same two teeth as the troll-ified goblins!
How I Lost My Mother - It's very faint and you can barely see it, but in the background, there are stuffed animals on Cronan's bed of a dragon and a teddy bear.
How to Build a Sweet Ride - In the background of webisode 23, Azari is painting the airship red!
Dragon Tale - Spark and Lula are looking awfully cozy there. 💖
Sizeable Refreshment - In Cronan's fortress is a portrait of himself . . . riding a unicorn. (First stuffed animals and now unicorns!?)
Bring The Heat - Azari throws her 'bling' out of the chariot, which includes a disco ball and (GASP!) the lava lamp that Emily gave her in Another Kind of Magic! 😢
Goblin Intern - Most of the goblins have eye-colours that either match their hair or their complexion, but there are a few exceptions.
The Final Battle - Tufflin hugs an injured Fibblin, which I thought was pretty adorable. But wait! They've also hugged before, in Evil Apprentice. I'm guessing they must be brothers, or best friends, or . . . something.
Season 4[]
The Enemy - Ragana drinks from a pink, heart-shaped straw which is the same straw Tufflin has in Sizeable Refreshment. Also, a page in her book shows that there are elemental symbols for light and darkness!
Toys in the Attic - There is a second guitar in the attic in a box of Emily's childhood toys. The guitar was likely child-sized and she outgrew it. There are also three other books in Grandma Jones' treasure chest, meaning that there could very well be three other major prophecies of Elvendale!
Relight My Fire - There's a fire extinguisher in Farran's treehouse (they've learned their lesson!) Aside from that, there's a giant net of apples hanging from the ceiling. But that's not all! In the Saving Sophie trailer, we can see that Farran has even more apples stored on his shelves. Why does he need so many??? I'm convinced that Farran has an apple addiction.
Focus - Aira and Cyclo came very close to killing Farran. He was swept off his feet as they flew by, and he almost fell off the floating island!
On a similar note, Cronan almost accidentally killed Dukelin in the Saving Sophie trailer. Cronan throws his golden goblet which hits Dukelin in the head, causing him to fall off the throne tower. Dukelin somehow miraculously survives the fall though it is unknown how, as the throne tower is quite high up.
