Stick-in-the-Mud was the grouchy brother of Bump-on-a-Log. All of the swamp ooze in the swamp is found around him, though he would never help anyone get any. Alexander's search for this brought him into the middle of a fight between the two brothers. Ultimately, the prince gave Bump-on-a-Log Rotten Tomato to throw. Stick-in-the-Mud and Rotten Tomato (who landed in the swamp ooze) hurled swamp ooze at the log. Afterwards, Stick-in-the-Mud apologized to his brother and all three promptly fell asleep. Alexander collected some of Stick-in-the-Mud's swamp ooze this from Bump-on-a-Log.
Stick-in-the-Mud is a character in King's Quest VI: Heir Today Gone Tomorrow.
