Arc Fatigue: His Fantasy Explorer Nitroid has been going on for quite some time now.
As of March 1, 2012 (Right after his Let's Play of Mario Adventure), he vowed to only focus on that game (Not playing any other Mario games) and keep going until he's beaten it. It took him 19 days.
In a video, raocow mentioned Rubber Fishy, whose Let's Play he was watching at the time, causing Rubber Fishy's subscriber count to subsequentally raise rapidly.
While she was quite popular in her own right, when Raocow told his viewers that PinkKittyRose was doing a deathless run of ASMT, her subscriber count jumped up.
Disappointing Last Level: Mushroom Kingdom Meltdown, a hack played by Raocow has a literal example of this combined with No Ending, the final world is basically an altered version of the first one, and then the game just ends right after the cut scene you'd expect to come before the final boss. No boss, just credits roll. Right when there's what seems like half the overworld not explored:
He used to run foobar during videos in his Google Video days, and occasionally sang along. Some of that was the Ear Wormiest of all.
Funny Aneurysm Moment: In his video for 75th place for Vanilla Contest '10, he states that he is glad his cat is not there.[1]
The tags for MKM vid 20 count not guest-featuring gaston the cat
Raocow's "hack" with Demo (Not to be confused with A Super Mario Thing, which was a collaboration project by Talkhaus), was this hack called "What the Hell?" Well guess who the Chargin' Chucks were?
Moe: If Raocow was the exact same person except for also being an adorable young girl, he would be the most famous person on the internet. Also most stalked.
Most Wonderful Sound: His laugh is so infectious, especially when he laughs really hysterically.
What Do You Mean It Wasn't Made on Drugs?: Note that Raocow is also straight-edge, meaning that he simply has a bizarrely appealing thought process. The art to a.t.x.s. does raise some suspicions.
You think a.t.x.s. seemed like it was made on drugs? You obviously haven't read Exupéry, adventures of.
The Woobie: The nature of Raocow's usual commentary means it's quite apparent when something actually begins to break him. Silent Raocow is one of the most heart-wrenchingly sad things you will ever hear. You want to reach over the Internet and give him a cookie or something.
His woobieness reaches new heights in this video. He just sounds so...dejected.
His cat died on June 25, 2010. In this video he sounds like he's sobbing in the background.
In this episode of SMWCP, he sets a woobie record. Usually, when he dies at the hands of a rather unfair level, you'll hear him swear in his native French or occasionally a moan or grunt of frustration. In this video (except for one emotional outburst) all of his frustrations are vented through strained, painful whining. It's like watching a kitten fail.
"That was the most unfun piece of crap that I've ever played in memory"
And that was saying that he considered the hack a break from games such as S. Mario, Mario Adventure, and Nitroid. The author heard a lot of complaints about the level (Not just from Raocow, but from other people too) and rehashed it so it could be slightly less harder.
↑Although he was saying that because the video had extremely horrible audio and that it would scare the cat.
