Heath lets his imagination run wild when a sinister message threatens to ruin the Friday the 13th dance!
Heath Burns is lost in a video game-fuelled daydream in which he is a brave knight defending his friends from the evil Sinisterian hordes. As he makes the villains run for their lives, his friend chant his name. This particular part of his daydream is not imaginary though, as his friends are calling him—they want him to lay down his video game and finally get to work helping prepare for the big Friday the 13th party.
Reluctant to leave his game, but eager for the party, Heath obliges and cleans some moss off of a rock. Doing so, however, reveals a message which Heath recognizes as Sinisterian in origin. He translates it for his friends as to read "On Friday the 13th of the 13th year, the Sinisterians will return to this spot to take over." Heath panicks and urges the dance to be cancelled, which none of his friends take well too. They point out that Heath has made wild claims before that only resulted in a lot of chaos about nothing. Heath swears this time the threat is real, but no one believes him.
Just as his friends start to leave, a portal opens on the message's spot and three Sinisterians walk out of it. Heath prepares to defend his friends as he did in his daydream, but the Sinisterians tell him to calm down; they are only here to take over the dance floor and party along! With the unexpected guests' arrival, the Friday the 13th party is declared started. Heath is left confused that the Sinisterians aren't actually evil, to which one of them replies that he should play less video games.
- Just before Heath burns away the moss on the rock, Gilda has her feet missing.
- It seems off for the webisode to visualize Clawdeen's recollection of the meteor incident, but not Draculaura's recollection of the Atlantis incident. Presumably, Draculaura's was to be animated in too, but ultimately cut for time.
