"Snail Shell" is a song by American alternative rock band They Might Be Giants. It was released on August 15, 1994 as the lead promotional single off of their fifth album, John Henry. It peaked at 19 on the Billboard Hot Modern Rock Tracks chart. This was a commercial disappointment for the band, as the song was perceived by the band as having the potential to be as successful as their breakthrough hit, Birdhouse in Your Soul. The day after the single's release, the group put out the E.P. Back to Skull, which features the song along with a version remixed by The Dust Brothers entitled "Snail Dust".
