Acid-spitting land squid

Acid-spitting land squids existed on the planet Drago 14 in the 27th century.

After the Eleventh Doctor took Amy Pond and Rory Williams there on 3 May 2698 for a "beach day" as part of their honeymoon, 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.
