Ice Cream Sand Witch

That's the only time we see her do it, but that doesn't mean it's the only time she's done it. That scene could've just been there to showcase it and the other times happen off-screen and/or before the start of the game (as in when the player makes an explosive entrance to Reborn). Just like we've only seen Julia boom something twice in-game, but we know she does it all the time.

There isn't a location list, but there's a list of which ones are obtainable that mentions which are wild and which are events. EDIT: Greninja'd

As of now, nothing can be done with it. Maybe Julia left a box of booms there.

Happy birthday! Here's an ice cream sandwich

It's hard for me to only pick one from Reborn's cast. The ones at the top of my list are Julia, Shelly, Shade, Radomus, Luna, Terra, Adrienn, and Amaria.

Yes, it's raised from 60 to 65.

In response to asks on Tumblr and in Twitch streams.

Ame has confirmed Julia is getting Oricorio, Shelly is getting Ribombee, and Shade is getting Mimikyu. I think there were a few others but those are the three I remember. I think Alolan Ninetales would fit Serra very well, and Alolan Dugtrio would fit Terra. I'm actually surprised Terra doesn't already have Dugtrio since wack-a-mole is a popular game and she has a mallet.

I don't believe what the false information is has ever been specified, just that she's been giving it to them for months. Here's what she says to Taka:

Ninia was in bracket 5.

I just realized! There's "the dream" mentioned at the end of the episode. Nova's goal also involves a dream. Sena's theme has Kirby. Dream Land is a kingdom in the Kirby games. Could Ayrith be in Dream Land? . o .

Neved used Minimize! Also, is that statue of Zapdos? . o .

Pokemon that disobey ignore orders sometimes, but not always. I started being overleveled before even Julia, and it wasn't until E16 that I decided I was tired of the disobedience and made an effort to stay in the level cap.

Where is Sena's from? Some parts of it sound like Kirby.

You can get Inkay, Murkrow, Starly, Sewaddle, Pichu, Feebas, and Joltik from it.

If it's the same as it is in the official games, level 39 during the day.

You're able to get Deino before Rosetta, yes. Here's the sidequest to get it: For Magneton, I assume you evolve it by leveling it up in the power plant, although I don't have one myself so someone else will have to confirm/deny it.

That's not part of a sidequest. She's been napping there since the end of E15. Probably she will wake up in the episode where we return to the mansion to battle Amaria.

For the secret ending:

I got the secret/perfect end

As an advance notice, I haven't 100% decided yet, but after the public release of episode 3 it's possible I may take a break before starting episode 4. I was a lot faster with episode 3 than I thought I would be, but I'm burned out from several periods of working on the game nonstop for hours at a time. And episode 4 will have a lot of eventing and mapping, since that's when the Sea Stars are visited and I want their civilization to be massive. That being said, I put a lot of effort in episode 3 and I hope people enjoy it when it's ready ^^' I'm currently working on a list of which Gen 7 moves and abilities are in the game (it'll be a notepad file like the marble location list and Pokemon obtainability list) to be ready by public release, and I may also make a TM location list since I'm starting to lose track of where I put them all myself. Legend Mode will come out some time after the public release, but I'm not sure when yet. SPB currently doesn't have wifi, so Legend Mode discussion will have to continue once she can use the Internet again.

You have to Fly to Reborn City.

There's not a list of TMs in the folder (or that I've seen, at least). I think Alilatias didn't mean a literal list and it was just a way of saying "You should see the new TMs added this episode".
