Oh Shiitake Mushrooms is a YouTube channel run by disabled parents Lee and Carole Powell, and their three children Leland, Leanna, and London, who are a dysfunctional family. Their webseries is called "Kid Temper Tantrum", focusing on Leland. Later they also have "Girl Temper Tantrum", which has Leanna. The channel is similar to Violette1st, McJuggerNuggets, The Angry Grandpa, and The Greatest Freakout Ever due to its videos involving destruction of property.
The channel provides examples of:
- Anti-Villain: Downplayed, since there's No Antagonist, but Uncle Jay sure does count.
- Big Bad: See Anti-Villain above.
- Breakout Character: Of course, Leland is in "Kid Temper Tantrum" which is included in almost every video.
- Catchphrase: Leland's "Don't post that on YouTube!" In the begnning of each video.
- Darker and Edgier: While the channel may be family-friendly and still have that comedic tone, it does not shy away from serious subject matter such as being disabled or being involved in fatal car crashes.
- Denser and Wackier: "Kid Temper Tantrum", with its crazy scenarios.
- Dysfunctional Family: The entire family has drama and problems non-stop. These are the subjects of every video.
- Elmuh Fudd Syndwome: Lee Powell, the father, has this.
- No Antagonist: Zig-Zagged. Leland, though he is a Nice Guy, does have moments where he destroys things.
- Punctuated! For! Emphasis!: "DON'T! POST THAT! ON! YOUTUBE!"
- Rotating Protagonist: Sometimes a video is about Lee, Caroll, Leland, Leanna Powell, or even London, the youngest.
- Tantrum Throwing: Sometimes, Leland or Leanna throw tantrums and destroy things. Even Lee falls into this trope, as he is known to say "I JUST WANT ONE NORMAL DAY!".
- Who Names Their Kid "Dude"?: The younger sister, London is named after the city in the UK.
- You Are Grounded!: Lee says and concludes this whenever Leland or Leanna get destructive.
