Fantastic Beasts in The Crimes of Grindelwald final trailer

In Grindelwald's escape scene the carriage is pulled by Thestrals. The Thestral tail hair 

was used to create the most powerful wand known by wizards, the Elder Wand.

You can see a snakelike beast to pop up also. Is this a Runespoor? 

Newt has two of them in his suitcase (FBAWTFT deleted scene)

In this scene Newt enjoys much riding the Kelpie. It reminded me the scene from 

'Harry Potter and The Prisoner of Azkaban', where Harry flew on the hipogriff's back.

Newt has a strong connection to this beast, an art poster recently revealed, that

his patronus is a kelpie.

"I have a love-hate relationship with that little guy... I thought he did pretty immaculately 

in his debut, but there’s a lot more Niffler to come. He looked so sweet and adorable just 

then, but don’t be fooled." - Eddie Redmayne at the MTV Movie Awards in 2016 

And the Niffler has babies in The Crimes of Grindelwald

"It’s probably been my favourite scene to shoot so far, the baby Nifflers,’ Eddie admitted. 

‘They’re just causing havoc and it coincided with the time that I now have a 15-month-old 

child and the baby Nifflers retain many of the same qualities!"

This is Eddie Redmayne's favorite beast Pickett the Bowtruckle that 

was kept by Newt Scamander as a pet.

‘I love the Bowtruckles so much,’ says Eddie Redmayne. ‘I think Pickett is my favourite character. 

He’s a bit of a loner within the family of Bowtruckles. He feels a bit bullied by his pals. He has 

attachment issues, so he keeps faking illness to hang out in my pocket. He is also incredibly agile 

and of great value. I use Pickett as a bartering tool with Gnarlak who runs The Blind Pig.’

Something went wrong, I'm afraid Jacob's in trouble again.

Kappa is a Japanese water demon that feeds on human blood. They are known for strangling 

humans that invade their shallow ponds. A Kappa was an attraction of the Circus Arcanus.

One can protect, and appease a Kappa by throwing a cucumber inscribed with that person's 

name; however, if they can trick it into bowing, the water in its head will spill out, weakening it.

Early in the MTV Comic Con cast interview Eddie Redmayne says with relief, there aren’t any 

too embarrassing moments with any creatures in the film. He admits, though, that this new beast, 

is Chinese and that he did film a scene where he speaks to it. "I was trying to attempt to […] 

speak some Mandarin to the Zhou-ou, but I think it’s been cut." (via: Mugglenet)

“The Zouwu is terrifying if you’re a normal human being and to Newt Scamander, like a big kitten. 

This is how it’s described in Chinese mythology: gigantic elephant sized cat, five-coloured. 

It really does take a Newt Scamander to contain and look after that beast.” - J.K. Rowling 

(via the-leaky-cauldron.org)

The location is the French Ministry of Magic

I wonder if they're trying to escape from a beast or from wizards here?

J.K. Rowling confirmed, that Grindelwald was a seer. This could be something that he saw in the 

future (aka World War 2 - these are not WWI planes) This might be Grindelwald trying to convince 

Newt to stop fighting by showing him what it would lead to. I agree with fantasticbeastsfanaticlove.

This was right after the war vision in the trailer, but I think this is from an other scene.
What's this beast? I think this is the Zouwu.
