Biography[]
Jeffy was first seen being called by Mario to tell him that he won fifty dollars with a plan to have ice cream. Once evetone gets their ice cream, Mario gets disappointed that Jeffy has a big cup with a higher price and tells him to eat the ice cream while giving him caution not to eat too much to avoid a brain freeze. Jeffy then asked what a brain freeze is and Mario tells him it was a painful headache as a result of eating ice cream too fast but Jeffy shrugs it off as a hoax. After eating the ice cream, Junior became shocked that Jeffy already ate the ice cream without having a brain freeze and continues to nit believe in a brain freeze. Decided to prove Jeffy wrong to go on a bet that brain freeze is real, Junior gets him to eat many ice cream he stole from his dad. Eventually, he suffered from a massive brain freeze that resulted to his skin turning blue much to Junior's horror and Mario comes in as he is in shocked about Jeffy's comditiin. Moments before becoming entirely frozen, Jeffy begins singing the song Blue by Eiffel 65 before succumbing to his condition and becomes frozen.
Mario calls Brooklyn Guy to come over and analyze the situation on Jeffy's condition. Brooklyn Guy gets the results and tells him that the only way he can be free of his frozen comdition is by thawing him out. Mario tries to thaw Jeffy out by taking him outside but Brooklyn Guy told him that it is October and the sun isn't out. Brooklyn Guy then tells Mario that he will have to wait for years for Jeffy to be unfrozen. Mario insists on putting him in an oven, but Brooklyn Guy keeps on telling him that it is illegal. Mario tries an alternate attempt to thaw him out using a hair dryer but to no avail as it has no effect. Rick comes him and makes the suggestion to take Jeffy's brain out and let it thaw out and construct a robot body for Jeffy to control.
By the year 3000, Jeffy reawakens in a robot body as he realizes what happen and learned that everyone is dead except for Mario and Morty (who is somewhere at space). He meets up with Mario who is now an eldery man and was unable to recognize Jeffy to him being a robot. Mario then reveals that he has a good life without Jeffy showing how much he hated him in the first place which emotionally hurts Jeffy. Enraged, Jeffy murders Mario by using his odor to suffocate him to death and begins a genocidal spree on exterminating all Marios in the multiverse. He then steals Rick's portal gun and travels to the Main Kable10 Timeline by going into the dimension using Time Warp and encounters the Mario of this dimension. He proceeds to attack Mario but this dimension's Jeffy witnesses the attack and tells him to stop. Realizing the potential disaster, he retreats to another dimension to continue his genocidal spree despite failing to kill this dimension's Mario.
