The shorts were shown as interstitials on Noggin and Nickelodeon during its Nick Jr. block. In the United Kingdom and Ireland, it aired on Nick Jr. UK, Noggin, and CBeebies. The show premiered on both Noggin and Nick Jr. Australia in 2006. Axial mesoderm cells under the ectoderm secrete inhibitory signals called chordin, noggin and follistatin. Examples of neural inducers are the molecules noggin and chordin. In the United States, "Oobi" aired on Noggin and Nickelodeon. It has been demonstrated that Chordin and Noggin dorsalize mesoderm. The organiser may produce molecules such as follistatin, noggin and chordin that inhibit BMPs. Both chordin and noggin are antagonists of BMPs. Migration of NCCs is primarily induced by BMP signaling and its inhibitor, Noggin. Other inhibitors involved in this process are noggin and chordin. The games on MyNoggin covered major school subjects and included Noggin characters. "Oobi" was instrumental in growing the Noggin network's viewership. It is also available for streaming on the Noggin app as of 2016. "Oobi" was a breakout success for Noggin.
