As a direct codicil to https://movies.stackexchange.com/questions/97048/can-i-watch-lego-movie-2-without-watching-the-first-part

Is the Lego Ninjago Movie required watching before seeing the Lego 2 Movie?

I thoroughly enjoyed Lego Movie 1 and Batman & understand there is some follow-on to the plot elements of these.  
Can the same be said for Ninjago, or is it a different universe/timeline?
