This guest at the Immortality Field Resort resembles @blips-and-chitz-patron seen watching @rick play the Roy video game at Blips and Chitz in Mortynight Run.

@progeric-student posing on a dead @worldender as @paperboy and others snap pictures.

Lots of previous characters making appearances at the party Rick planned after killing @worldender, including @mitch, @reality-show-cynthia, @nancy, @half-shirt-suspenders-student, […]

In Morty’s Mind Blowers, @truth-tortoise appears to mumble something incoherently to @morty, but if you reverse the audio you’ll hear the message I’m a Beatle, Paul is dead, which is homage to the Paul is Dead […]

In Get Schwifty, we find out @rick was in a band with @birdperson and @squanchy called The Flesh Curtains.

I initially thought I inadvertently added this user twice; once as @curse-purge-plus-student-employee and again as @high-fiving-student. However, two different people were seen in the post credits clip from The […]

In the post credits sequence of Something Ricked This Way Comes, the @religious-idiot is holding a God Hates Fags sign, but watch closely and you’ll see it change to God Hates You for a brief moment.

We know @squanchy had @tammy trapped in The Wedding Squanchers, but then at the end of the Rickshank Rickdemption we see @tammy again with @phoenixperson, but the fate of @squanchy is unknown.

Besides @toby-matthews and @summer, we see three other Harry Herpson students in this shot of Summer’s second party; @mitch, @progeric-student, and @paperboy.

Another familiar background character, @mrs-tate, was quick to accept Headism.

Hard to tell who is present under the specific circumstances of the @cromulon arrival (likely @rabbi) and who would have been at church anyway, but we see some familiar faces in the pews with @vagina, […]

When @jerry thinks @beth and @sleepy-gary are married, he apparently is unaware of the pictures of him in the background instead of @sleepy-gary. Also, if he says “I know who the Smith’s are…”, does that mean […]

Here is @curse-purge-plus-undead-cat-and-child-customer at the Headism meeting discussing the Ascension Festival.

We see @round-glasses-nasa-scientist in the room when @cromulon shows up, then later we see her when @rick sends plans for an interstellar vehicle from the Menagerie of @the-collector. 

@mr-meeseeks can be seen in the background at Blips and Chitz.
