WIGGTY WIGGITY WUZZ'UP DUDE BROS? IM HERE WITH A NEW DESIGN 4 YO!

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 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.
