„I Feel So Blue“ je píseň, která se objevuje v epizodě The 7D, „Grim the Genius“. Zpívá ji Grim Gloom, zpívá, jak se kvůli své hlouposti cítí modrý a přeje si, aby byl chytřejší, než je teď.
Grim: I feel so blue
Frog: Ribbit
Grim: I’m bluer than my hair, so blue
Frog: Ribbit
Grim: I mess up everywhere I try to do what’s right
Frog: Ribbit
Grim: But I’m just not that bright, I mess up day and night, sad but true
Frog: Bo-hoo
Grim: I feel so blue
Frog: He’s blue
Grim: Cause Hildy’s mad at me, I better come through
Frog: Come through
Grim: Wriggle in bad
Frog: Ribbit
Grim: Oh if I was smart, then Hildy’s heart will love me through and through, but I don’t have a clue
Frog: Ribbit
Grim: And that is why I feel so blue
Frog: He’s blue
