text: During the promos, Henry's hair looked slightly different in some shots, along with it being a different shade of green. June's cardigan was cherry-red instead of light red/dark orange, and the dots weren't visible. Also, their eyes were blue and green in every shot, instead of being black or blue (or green) and black.
  Broadcast
  KaBlam! first premiered on October 11, 1996 and ran for four seasons, totaling 48 episodes. The final episode was broadcast on May 27, 2000. Reruns continued to air on Nickelodeon until 2001.
  In 2002, Nicktoons was launched, and the channel began airing reruns of the program, though not all episodes were aired. During commercial breaks, various shorts from the show would play, not including any shorts involving Henry and June or music videos. In September 2005, Nicktoons revamped its branding and schedule, and removed several older series in the process, including KaBlam!. The "KaBlam! Presents:" shorts would continue to air until 2008 when the channel removed all of their intersitial programming for more commercial space. The program would only be seen one more time in December 2007 for Nicktoons Network's "100 Greatest Nicktoon Episodes" marathon, although it was not shown when Nick had a marathon of the first episodes of each Nicktoon on Thanksgiving Day 2007, despite having Henry and June on the cover of the now-defunct Nickelodeon Magazine.
