|Examine||A Ga'al explorer.|
Captain TzHaar-Ga'al-Knot is a castaway and a TzHaar-Ga'al that can be found on a special uncharted Springbreak Island when the player reads a message in a bottle and receives a treasure map written by Captain Knot. When found, they will give the player one taijitu. TzHaar-Ga'al-Knot references The Harbinger, describing it as a ship with black sails that stranded him on the island after he charted a ship from Karamja.
The message in a bottle to locate this castaway was last visible 1 day ago on 16 October. It will be visible again in 4 days on 21 October. (wrong?) Once a message in a bottle is found and when a player has walked near its spawn location when it was visible it will always be visible, unless the message in the bottle or its treasure map is in the player's bank or inventory.
- The dialogue option "What's a nice Ga'al like you doing in a place like this?" is a reference to the 1963 Martin Scorsese short film What's a Nice Girl Like You Doing in a Place Like This?.
- Comments that the Ga'al is "easier to find than I expected" are a reference to the TzHaar-Ga'al-Kot, which was released as an easter egg in early 2013 and took five months to find despite repeated clues from Mod Stu.
