Drago 14

Drago 14 was a planet with a beach infested with acid-spitting land squids.

The Eleventh Doctor took Amy Pond and Rory Williams there on 3 May 2698 for a "beach day" as part of their honeymoon, but they quickly called him to ask him to pick them up again after the beach was overrun by squids who melted Rory's Terry Pratchett book with their acid. (PROSE: Honeymoon Horrors)
