This series features Easter eggs of several Cartoon Network shows. For example:
- In Hermit Crab Havoc, while Claire was reading a book, a demon similar to Aku from Samurai Jack can be seen on one of the pages.
- In the same episode, a clip of a Regular Show episode was briefly seen on the television.
- In a flashback in Merry Christmas!, kids similar to Robin Snyder, Mitch Mitchelson, Elmer Sglue, Harry Pitt and Mike Believe from The Powerpuff Girls were seen in the mall in Claire's flashback.
- In George Duck, George shows Eric pictures of what he was doing after he escaped from the lab he was in. One of them showed Chupacabra chasing him, and Eric responds, "Wait... doesn't he look familiar?", referencing to The Cryptids and the crossover the show and Eric and Claire had.
- In Return of the Spooker, a broken frame with the Grim Reaper from The Grim Adventures of Billy and Mandy can be seen in a trash can.
- In the same episode, there is another Billy and Mandy reference, where we see Claire try out what appears to be a costume of Billy.
- In Ghost-Napped, dolls similar to Princess Bubblegum, Marceline and Flame Princess from Adventure Time were seen on the floor.
- In Internet Screamer, an action figure resembling Zoko from Mythical can be briefly seen.
- Eric and Claire takes place in a fictional city of Strangon, Ohio.
- The only characters who know about Claire actually being a ghost and not a regular human besides Eric are Brandon and Michael, but as time goes on, more people start finding out, for example:
- Llamy the Llama in Llamy the Llama.
- The Cougarman in The Cougarman of Strangon
- The Cryptids, Dr. Turbo, and Angel the Bald Eagle in the crossover special, The Cryptids, Eric, and Claire.
- Elizabeth in The New "Friend".
- Madame Freakshow, her sidekicks, and the Spider Thing in Carnival Paranormal.
- Emily McEdderson (though she forgot about it after being knocked out) also in Carnival Paranormal.
- George Duck in George Duck.

- Jessica in Jessica.
- The Woodson siblings, Tyler, Julia, Professor Woodson, Tiffany, and Ghostly in Out of Normal Activity.
- Madame Freakshow is claimed as Eric and Claire's arch-enemy starting from "Carnival Paranormal", though before that episode, it was Brody and his gang that were their main arch-enemies.
- Darren Criss is a special guest star for his portrayal of The Music Monster from High School Not-So Musical.
- About a month later, another special guest star, "Weird Al" Yankovic, appeared to portray as Tiny.
- There were rumors on the internet that unlike Season 1, Season 2 will become more gruesome, horrific and graphic, so much compared to a horror film, that it'll move from Cartoon Network to Adult Swim with TV-14 (or even TV-MA) episodes. However, the creator responded to the rumor saying it's false.
- Dolofonia in Ms. Dolofonia's name is actually Greek for "Murder".
- Christopher Tally went through some changes in the show. Originally, he was gonna be an anthropomorphic shark that was turned into one by Michael's experiment back when he was a human. Next, he was changed into an anthropomorphic bulldog. Then, he was changed into a human like he is now, but was originally gonna be one of Eric's friends and one of the main characters, but finally, he was changed into a recurring character and overall the main antagonist in The Chick for Christopher.
- Eric McEdderson was originally gonna be named "Edward McEdderson" and the show was supposed to be called "Edward and Claire".
- The character, Jason Badluckpants, was originally intended to be a real life antagonist until Craig decided that he fits more as a fictional character in Polly and Horsey.
- Cartoon Network Studios: the logo shows Claire sneaking up on Eric and scaring him, as Claire then chuckles while Eric glares at her.
