On 7 October, 2017, a new episode for season 7, entitled "Once Upon a Zeppelin", was released, and many people noticed a background pony that looked similar to Chris, and two more in the background that looked similar to Barb and Bob.
Ironically, the episode's story was about Twilight-Sparkle learning that her parents have won a free zeppelin cruise for their family. Upon boarding, Twilight discovers the cruise to be a vacation experience where the other passengers pay to spend time with her, invading her and her family's privacy.
The pony in question is a grey unicorn, with pedo glasses, a striped shirt, and a receding light green mane. Humorously, he is the only character in the audience to not smile when Twilight announces the winner.
The speculation about the pony was noticed by Chris, who commented:
I was just made aware of this speculation from the MLP Zappelin episode. I highly doubt that Unicorn was based from myself.
The only way to confirm or bust this is by the testimony from Tara or someone official on the MLP staff.
Aside from that, I would rather be on there, personally voicing my OC pony, Night Star. Sidenote towards the relevance of the cameo:
CWC gained infamy in regards of his participations in potens from an early age. When he was in elementary school age, he won a Wal Mart contest for a 1.000,00 $ Shopping Spree for SEGA Merchandise. He was later interviewed on regional television for this. It is suspected the organizers let him win out of pity due to his mental condition. It is also speculated this event fed into his delusion of being a special Sonic Fan.
Chris went later on to take part on in a Music Contest held by Sony for a Parappa the Rapper game. Despite getting into the top 10 of finalists, he ungraciously lost. Being a very sore loser about it, He later created a website to shame Sony, declared himself to be the true winner and send death threads to the actual successor and his underage sister.
