Most people don't know that The Incredible Hulk wants to spend some quality time with a ukulele. Nuclear Bubble Wrap knows and they wrote a song about it. The tune follows Hulk as he tries to fulfill his goal, and throughout he is thwarted by his own size and the jibes of Spider-Man and Wolverine. There's a bit of sulky Hulk in the lyrics but the green guy does okay in the end.
Hulkulele is a gentle tune led by a keyboard in steel drum mode, highlighted with ukulele riffs, and possessing a hint of Caribbean sound. As told by NBW's Jace, "one of my roommates has a pair of Hulk hands. Another one has a ukulele. Somehow that led to this song existing."
The current version of the song was released in February 2012 as a sort of pre-release version. Jace stated on WeirdAlForum.com that the song was due for a "drastic overhaul" to "make it sound a lot more like a reggae song" in an effort to match the tone of then-upcoming album Psycho Delicacy. Instead the song was released unchanged on the Abracadaver EP in April 2012.
