Bump-on-a-Log resides in the swamp of the Isle of Wonder, a sentient log with a bump on the top of it. He is lazy, unable to move and constantly under barrage by the temper of his brother Stick-in-the-Mud. When Alexander sought swamp ooze, Bump-on-a-Log patiently explained to him that it was all located out by Stick-in-the-Mud. this resulted in the Prince of Daventry becoming inadvertently caught in an argument between the siblings. He handed Rotten Tomato to the log as ammunition, should his brother become too much to bear. Unable to hold himself back, Bump-on-a-Log hurled the overripe fruit at his brother. Both Stick-in-the-Mud and Rotten Tomato began hurling swamp ooze back at the log in retaliation until all three were exhausted.
Bump-on-a-Log is a character from King's Quest VI: Heir Today Gone Tomorrow.
