I do remember. Hippogriffs went underwater since the Storm King invaded Mount Aris, Queen Novo use her magic pearl to transform herself and her entire race, including her brother-in-law Sky Beak, her sister Ocean Flow, her niece Silverstream, her nephew Terramar, her daughter Princess Skystar and her subjects into Seaponies, abandoned her kingdom home and build new underwater kingdom, Seaquestria.

After the Storm King's defeated, Queen Novo divided her pearl into hundreds of fragments, allowing her race to switch their forms back and forth. Some of her subjects return to rebuilt Hippogriffia and repopulate Mount Aris while her other subjects stay in Seaquestria and remain as Seaponies.

That's what the illusions of the Storm King and his army still haunt Silverstream that I've saw in the animatic trailer.
