New Gups


  • Darragh O’ Connell, a director on the show from Season 1-4, confirmed that he’s had no part in Season 5’s production, as stated in this tweet.
  • The delay was most likely caused by airdate traffic from CBeebies. Some footage and images of Season 5 have been found in various Chinese websites. It is currently unknown when it will be released in English.
  • The seasons further delay in other countries after its China premiere in 2021 may also be due to behind-the-scenes production issues. Meomi's lesser involvement, adjustments to the switch in studios (from Brown Bag Films to Mainframe Studios, previously known as Rainmaker Studios at the start of production), contracting issues (China’s new involvements, the Netflix deal), the production of the movies and Above & Beyond, working under pandemic conditions, and much more can be speculated as causes for the long-term delay, despite the project supposedly wrapping up at some point in 2018 or 2019.
  • Due to the delay, and despite its events occurring before those in the spinoff series, Above & Beyond's first season has debuted on Netflix worldwide. This may leave room for confusion when Season 5 finally releases with Min's original introduction, Periwinkle still being a baby, the Gup-R's first appearance, and plenty more.
  • Though Season 5 is now debuting after Above & Beyond, it technically hosts Calico Jack, Pearl, Periwinkle, and Professor Natquik's first time appearing again since their debut episodes.
  • In February 2017, an Octonauts Scaly-Foot Snail toy was released, which was the first Season 5 creature and episode hinted. In September 2017, a printing file was released featuring Season 5 and a Yangtze River special information, and a new special character (Mapmaker Min) was revealed. News on the Coconut Crisis and Sunfish episodes' broadcast delivery to all channels featuring the Octonauts show was released because of it.
