<P> To date, eight seasons (totaling 84 episodes) have been produced, along with two pilot episodes, six mini movies and one extended special . </P> <P> The two pilot episodes were aired in January 2011, coinciding with the launch of the Lego theme . Their popularity led the first two full seasons (' Rise of the Serpentine' and' The Green Ninja') to be commissioned . These each consisted of 13 episodes . Both the Lego theme and the TV series had an intended shelf life of three years, so it was expected that the second season would be the last . However, after comments from fans, it was soon revived and has been in production ever since . </P> <Table> <Tr> <Th_colspan="2"> Season </Th> <Th_colspan="2"> Episodes </Th> <Th_colspan="2"> Originally aired </Th> </Tr> <Tr> <Th> First aired </Th> <Th> Last aired </Th> </Tr> <Tr> <Td> </Td> <Td_colspan="1"> Pilot Episodes </Td> <Td_colspan="2"> </Td> <Td_colspan="2"> January 14, 2011 (2011 - 01 - 14) </Td> </Tr> <Tr> <Td> </Td> <Td_colspan="1"> </Td> <Td_colspan="2"> 13 </Td> <Td_colspan="1"> December 2, 2011 (2011 - 12 - 02) </Td> <Td> April 11, 2012 (2012 - 04 - 11) </Td> </Tr> <Tr> <Td> </Td> <Td_colspan="1"> </Td> <Td_colspan="2"> 13 </Td> <Td_colspan="1"> July 18, 2012 (2012 - 07 - 18) </Td> <Td> November 21, 2012 (2012 - 11 - 21) </Td> </Tr> <Tr> <Td> </Td> <Td_colspan="1"> </Td> <Td_colspan="2"> 8 </Td> <Td_colspan="1"> January 29, 2014 (2014 - 01 - 29) </Td> <Td> November 26, 2014 (2014 - 11 - 26) </Td> </Tr> <Tr> <Td> </Td> <Td_colspan="1"> </Td> <Td_colspan="2"> 10 </Td> <Td_colspan="1"> February 23, 2015 (2015 - 02 - 23) </Td> <Td> April 3, 2015 (2015 - 04 - 03) </Td> </Tr> <Tr> <Td> </Td> <Td_colspan="1"> 5 </Td> <Td_colspan="2"> 10 </Td> <Td_colspan="1"> June 29, 2015 (2015 - 06 - 29) </Td> <Td> July 10, 2015 (2015 - 07 - 10) </Td> </Tr> <Tr> <Td> </Td> <Td_colspan="1"> 6 </Td> <Td_colspan="2"> 10 </Td> <Td_colspan="1"> June 9, 2016 (2016 - 06 - 09) </Td> <Td> July 15, 2016 (2016 - 07 - 15) </Td> </Tr> <Tr> <Td> </Td> <Td_colspan="3"> Special </Td> <Td_colspan="2"> October 29, 2016 (2016 - 10 - 29) </Td> </Tr> <Tr> <Td> </Td> <Td_colspan="1"> 7 </Td> <Td_colspan="2"> 10 </Td> <Td_colspan="1"> May 15, 2017 (2017 - 05 - 15) </Td> <Td> May 26, 2017 (2017 - 05 - 26) </Td> </Tr> <Tr> <Td> </Td> <Td_colspan="1"> 8 </Td> <Td_colspan="2"> 10 </Td> <Td_colspan="1"> April 21, 2018 (2018 - 04 - 21) </Td> <Td> May 20, 2018 (2018 - 05 - 20) </Td> </Tr> </Table> <Tr> <Th_colspan="2"> Season </Th> <Th_colspan="2"> Episodes </Th> <Th_colspan="2"> Originally aired </Th> </Tr>
