Jeffy has to make a rap song to win a contest!
Jeffy is playing with his cat piano, singing to the tune of "Mary Had a Little Lamb" but as a diarrhea version of it called "Tacos Gave Me Diarrhea". Goodman comes to the house and tells Mario that his house payment is due, and if he doesn't pay it, he'll give him a "purple nurple".
Mario goes back to Jeffy who is playing his cat piano and explains the problem. A commercial comes on, announcing that there is a rap competition for fifty thousand dollars. Mario tries to make a rap and fails, and then Jeffy says that he can do it. Mario says that he can't do it. But Jeffy insists that he can and tells Mario he needs a saxophone. Jeffy makes a rap called "Wanna See My Pencil?". Jeffy submits the song, and Mario thinks that he will not win.
The doorbell rings and Tyrone tells Mario that Jeffy won the rap contest. Tyrone starts to hand Jeffy the money, but Toad appears and tells him that he can make a better song. Toad finishes his song, and Tyrone really likes it and starts to consider a tie. He then says that they should call a fireman to see which song is the most fire. Brooklyn T. Guy as the fireman comes in, and listens to both songs, and likes Toad's better. Mario gets upset that he didn't get the money, but Jeffy then takes out ten thousand dollars that he stole so that Mario can pay his house payment.
- This is the first video of 2018.
- In a blooper video on SuperLuigiLogan, a more profanity-laced version of Jeffy's “wet kitty” scene was shown. Logan stated that this was not a blooper, but rather how he would have done the video if he was not under the threat of age restriction.
- This is one of the rarest videos where Mario and Toad interact with each other.
- A clip of Toad's Music video was shown on Instagram 3 years ago. It was originally going to be a Toad and Ray Cheesy Music video uploaded in 2015 but was scrapped.
- Toad's song was first shown on YouTube from "Bowser Junior's Summer School 3" as Educational Music Video by Toad.
- This video breaks the streak of videos without cussing, as the word "ass" is said multiple times in Toad's music video. The streak would be re-instated in the next video and would remain for two more months.
- Jeffy and Toad's raps could be considered a comparison with 2 common rap styles of this generation; Jeffy's rap could be based off of lyrical rappers, and Toad's rap could be based off of mumble rappers.
- Additionally, Toad's rap won the competition. This is like how rap talking about women, money and cars is more popular than rap with meaningful lyrics nowadays.
- This is Toad's first speaking appearance since "Bowser Junior's 9th Birthday!".
- The bat Jeffy uses in the rap to hit the green bean can is the same bat used in "Jeffy's Birthday Wish!", "Jeffy Plays Minecraft!", and later, "Zombie Bowser!".
- This also means Jeffy still hates green beans, despite what happened in "Jeffy And The Beanstalk!". that or Logan forgot about it or it took place before that video or he just put it in there for laughs.
- This video was uploaded 2 years after Mario's Turtle Problem!, 3 years after Bowser Loses His Voice!, and 4 years after Chef Pee Pee's Father.
- This is the second Jeffy the Rapper video.
- Lil Whine is a parody of Lil Wayne.
- Goodman says that he would twist Mario's nipples around town, which is a reference to the SpongeBob SquarePants episode Bubblestand where one of the techniques to blow good bubbles is by "bringing it around town".
- Logan uploaded the video as JeffyRapper2DONE without a custom thumbnail.
- You can see green specks during the rap at sometimes.
- Logan's hair was shown for a few frames in the rap song.
