K'nuckles' Song (AKA I'm All Alone) is the featured song in the episode, Come Home Cap'n and canon. Even though K'nuckles doesn't sing much in the series, this is his first offiical song. All alone, K'nuckles sings about how lonely he is and needs to go back to Flapjack. This was to support about K'nuckles' feelings.
What is happening to me? I'm feeling a bit strange,
Is it possible that I lost it all and my life's gone down the drain?
Do I really need to change? Now that I'm on my own, I'm feeling all alone.
I live in a crate, and ain't that great, and I'm freezing to the bone.
I wish I can go back home. Oh Bubbie, Why did you kick me out?
I got a raw deal, and now I feel that I'm the odd man out.
And Bubbie, How I wish that I can come back.
Cause your warm insides makes me warm inside, your heartbeat keeps me on track, and
I guess I miss you and Flapjack.
Do you see, Do you see, Do you see Bubbie?
Sleeping peacefully there and I bet she's not aware.
How much I'm in despair, and how I wish I was in there.
