Emerald Sea
From Tardis Wiki, the free Doctor Who reference
The Emerald Sea was an ocean on the planet Fragrance. Exactly what liquid comprised it was unclear, as water on the planet was described by its inhabitants as being "like wine", while the sea was bright green. On its shores, Rhythm committed himself to the Fragile Yellow Arc by confessing his love to Barbara Wright and by kissing her for the first time. (BFA: The Fragile Yellow Arc of Fragrance)
