The knights are tasked with protecting the King's valuable Ned Knightley comic book during the Bookingheim Knight-a-Con. But with all the costumed kids there, will they recognise the real Jestro and Book of Monsters coming to get them?




  • This episode marks the debut of Robin's Mini-trex.
  • The character Jokes Knightley is introduced as Jestro’s idol and a washed up comedian, sharing the same voice actor with Krux from LEGO Ninjago.
  • Jestro is revealed to have never went to the Knight-a-Con before ever since he was a kid.
    • He is also shown at the end of the episode that he is able to balance on a barrel without falling.
    • If one looks closely, one of Jestro’s plush toys-a unicorn is seen in the little girl’s room at the end of the episode.
  • The event in the episode, Knight-a-Con was a wordplay of the San Diego Comic Con. Coincidentally, Comic Con was one of the main events where most of the Lego theme products was shown and displayed; Ninjago and Nexo Knights.
  • The theme Robin plays on the Mini-trex is Nexo Knights theme song, Unbreakable without the lyrics.
  • This is the first time the Nexo Knights succeed in preventing the Book of Monsters from eating his intended meal (in this case, the Ned Knightley comic book).
