"Galactica Tsunami" is an attack used by Sailor Aluminum Siren in the manga, anime, and musicals.
It is unclear whether the unnamed attack Siren uses after the initial blast is part of Galactica Tsunami, but it uses a long thick substance to wrap around Sailor Mercury and Jupiter's bodies and strangle them.
In the anime, it was more of a gag than an attack. Sailor Aluminum Siren simply throws various drinks towards the Sailor Guardians.
This attack only appeared in Kakyuu-Ouhi Kourin.
