Secrets

  • Secret Level/Complete Standard Galactic Alphabet Translation

    To access the Secret Island, you must wait at the shore just south of the Grand Intellect's Castle. Messie, the monster you may occasionally see swimming on the map will swim up to it. This may take several minutes. Walk onto Messie to hitch a ride and it will eventually take you to the Secret Island. The level here contains both hordes of Stuffed Toy VortiNinjas and the first of two complete translations to the Standard Galactic Alphabet in the entire Keen series.
