The Kerplunkett Peninsula, or Ostrad Peninsula, was a peninsula on Naboo between Otoh Gunga and the swamp of Lake Paonga.[1]
Behind the scenes
Kerplunkett Peninsula and Ostrad Peninsula likely refer to the same location. The game book discusses going around the Ostrad Peninsula if the reader takes the safe route, then in the safe route section calls it the Kerplunkett Peninsula instead.[2]
