Foxtail Socks is the 7th stage in Soundodger+ and like most of Bill Kiley's songs, is composed of chip-tune notes, with a harp solo at the end. The song itself is very upbeat and chipper. It contains no vocals.
The song has 7 enemies and uses the bubble bullets more then any stage before it. The stage is difficult for a difficulty 2 stage. Harder then any stage before it with an exception of Dummy with may be the same or less difficult. It is also exceptionally short at only 2:41.
