South Park and adidas joined forces to celebrate 4/20 in 2021 with the release of the adidas Campus 80s South Park Towelie. This release references Towelie, a laboratory-made, cannabis-consuming towel character who has made appearances in more than a dozen episodes and three South Park games.

The adidas Campus 80s South Park Towelie features a purple terry cloth upper with white leather overlays and purple leather lining. Towelie’s eyes appear on the tongue and when exposed to sunlight, they transition from white to bright red. A hidden stash pocket in the tongue is big enough to fit the Towelie keychains that are included with the shoes. Quotes from Towelie that read "Don’t Forget To Bring A Towel" and "I Have No Idea What’s Going On" also show up on the tongue’s interior. A white sole and adidas branding on the heel tab complete this South Park release.

The adidas Campus 80s South Park Towelie released in April of 2021 and retailed for $100.
