The 2013 10th Anniversary Nickelodeon Chormentune logo is actually similar to the 1989 10th Anniversary Nickelodeon logo but with the 2009 logo. (The 2023 20th Anniversary Nickelodeon Chormentune logo actually has a different cake as it may remind you of the 1999 Nickelodeon 20th Anniversary Logo). It also aired Octonauts (as well as Nick Jr. The Channel) but then aired on Playhouse Disney Channel since July 2011. On March 2, 2007, most of the chormentunese TV channels alongside Nickelodeon and Nick Jr. Chormentune have switched to 16:9.
