| Please note the following:
- For the video of the same name, see Drawing Jeffy!.
As his names implies, Drawing Jeffy is a deformed version of Jeffy who came to life from originally being a drawing. He has a deeper, louder voice and likes saying the word "Mayonnaise". He is more stupid than Jeffy in a way, and wears a mayonnaise lid as a helmet. He likes to pretend that he is a meatball. He is shown to really like mayonnaise as he wears a mayonnaise cap on his head instead of a helmet.
It is suggested that the reason for his mannerisms is because of how poorly Bowser Junior drew him.
Drawing Jeffy was originally from a fan mail video in which they opened it, and Logan found it was so funny that he immediately made a video with it.

- Drawing Jeffy is shown to hate Gumbo, Bowser Junior's imaginary friend along with Simmons.
- Logan has said that he considers Drawing Jeffy to be funnier than the real Jeffy.
- According to Logan, each time Drawing Jeffy appears in a video, he has no memories of the previous videos he was in.
- Drawing Jeffy appears to be made out of a Kermit the Frog puppet; not only does his mouth have the same shape, but the edge of his mouth is partially green.
- Drawing Jeffy bears some similarities to DoodleBob from SpongeBob SquarePants, as both characters are a drawing of someone else that came to life, have caused mayhem to others, and both can barely speak English. Because of this, it is likely that Drawing Jeffy is based off Doodlebob.
- In addition, in his first appearance he was defeated by getting trapped inside a piece of paper just like Doodlebob in the Spongebob episode Frankendoodle.
- Drawing Jeffy also acts similar to Ed from Ed Edd N Eddy and Mr. Conductor's Evil Twin from Shining Time Station.
- Drawing Jeffy has been shown to have a strange obsession with mayonnaise, as seen when he says "Mayonnaise!" while hitting his mayonnaise lid, in addition to the scene in Jeffy Sneaks Out where he empties out several jars of mayonnaise and flails the mayonnaise around with a spoon.
- He is also shown to hate bananas, as seen in Jeffy Sneaks Out. This may be the equivalent to Jeffy's grudge he has toward green beans.
- He appears to be much more unintelligent than Jeffy.
- Mario and Rosalina do not recognize that Drawing Jeffy is not the real Jeffy, whenever he is around them, they will think that it is the real Jeffy. However in his most recent appearance in Mario Sells Jeffy!, Mario and Rosalina could actually tell him apart from the real Jeffy
- It is unknown what happened to him after Jeffy's Home Alone!.
- Drawing Jeffy strangely has an odd tendency to run away for no reason after being summoned.
- In Jeffy's Summer School, some fans realized how he was starting to sound like Black Yoshi, despite his response, "Pufus", this could be because of how Lance voices both characters, thus they sound similar because of that.
- Due to him being a murder and Logan is now family-friendly, it was thought that he would not appear in future videos. However, Drawing Jeffy did make a comeback in 2020 in Mario Sells Jeffy!. He was previously going to make a possible comeback in The Baseball Game! but did not most likely due to time constraints.
