In "Weirdmageddon 2: Escape From Reality," Dippy Fresh first appears in Mabel's office when Dipper and Mabel begin to argue. He was created by Mabel as backup Dipper with a more supportive attitude in case the real one didn't agree with her. He entered as the twins were talking about escaping Mabeland, stating he likes skateboarding, supporting Mabel, and punctuating every sentence with a high-five (which Soos does with him). Dipper develops an instant and intense hatred for him.
He later appears in Mabeland court when Dipper is tried for mentioning reality, with Dippy Fresh set up as a replacement for Dipper if Dipper should lose the trial. When Dipper and Mabel reconcile in court, and Mabel decides to return to reality, Dippy Fresh, along with the other imaginary creatures, turn against Mabel and chase down the twins, Wendy, and Soos to prevent them from escaping.
Though being physically similar to Dipper, Dippy is different in personality, as he is cooler and more laid back as opposed to the real Dipper.
Dippy Fresh looks like Dipper, but with major differences. He dresses in heavily 90's-inspired attire and has the same t-shirt and hat as Dipper, but Dippy's hat is backwards and his shirt is tucked into his pants. Both items of clothing are also more brightly colored than Dipper's. He wears grey jeans, a fluorescent green belt, green and pink high-top sneakers with blue lightning bolts and red flashing lights, a blue vest with yellow lightning bolts, and a pair of visor-like green sunglasses with purple lenses. He sometimes also wears a purple helmet with a blue stripe down the middle.
- He bears a striking resemblance to Kid Vid, a character from old Burger King advertisements.
- His appearance inspired someone called Crayon Queen to make a new alternate-universe undertale character called Fresh Sans.
