The Vat of Acid Episode
Since we’re on the topic, we have another note-worthy Easter Egg from the iconic episode. You may have noticed the title stands out; we’ve mentioned before that starting from the sixth episode of season 1, the episode titles all include the names of either Rick or Morty (and often both). However, while this is a season 6 episode, the title doesn’t include the caracters’ names.
That’s not the only thing different about it. Unlike every other episode on the series, in this one, the title of the episodes appears in the title card of the show. Fans suspected this suggests this would be a bottle episode – a minimalistic episode which takes place in one room, featuring a small number of characters with minimal epcial effects. However, that wasn’t the case, as Rick and Mortu didn’t spend he entire episode inside the vat of acid. However, it did become one of the most popular episodes of the show.
