Halalka
From Tardis Wiki, the free Doctor Who reference
Halalka was a planet visited by the Eighth Doctor and Molly O'Sullivan. They were chased by the Daleks during their visit there. The anti-grav waves on the planet were held up by artificial gravity generators. Dolphin-like animals were native to the planet, and had become used to the gravity fields. (AUDIO: Fugitives)
