This song is featured in Dear Diary. While Flapjack was working on his diary, K'nuckles dreamed about what was in it. Some footage has four Flapjack angles, a museum and Flapjack kept saying "Land". Here are the lyrics to the song":
Captain K'nuckles, the greastest in the world,
With courage and honor, his glory should unfurm.
His beauty are moving, his skin and skills are grand,
He's Captain K'nuckles, the finest adventure in the land.
(Flapjack keeps repeating land).
