Marine Song 2001

"Marine Song 2001" is one of K.K. Slider's songs. It is based on the tune Kapp'n sings in the original Japanese version of, which was altered in all localized versions to a tune based more on western sea shanties. The number "2001" in the song's title alludes to the year that both and the Japanese version of Animal Crossing were released. The aircheck version is by far the longest of K.K. Slider's songs, as it continues without looping for nearly three and a half minutes.

Ankha, Coach, Joey (in ), Scoot, and Mott have this song playing in their houses. It also plays in Kapp'n's taxi in (a remixed version officially referred to as "Heavy Rotation"), his bus in, and in his RV in.
