Underfresh is an AU where everyone speaks in l33t (leet/internet language) and is traditionally draw in a MS paint scribble format, though any other way is fine. Everyone wears 'swag' clothes and sunglasses, uses skateboards, and protects the impressionable youth from doing drugs. There are a lot of bright colours and explosions as well. This AU has also recently turned into a sort of 'infection', which means there is an Underfell version of this as well.
About the AU
In this world, it’s sk8 or be sk8. This AU is a comedic parody of Undertale characters as 90′s skater culture mixed with the meme culture of the 2010′s. All of the characters wear bright pastel colors and have various sayings, slang, and memes all over their attire. Papyrus is the only one unchanged, still wearing his Cool Dude attire.
