Mixed Lollies, a group which likes to do impromptu stree performances as sharks in Australia. According to their website they also use shiny, slippery, scooters. There are also images of their younger ballet group dressed as sea anenomes...
Also discovered the Whale Shark Festivals of Mexico (they do everything I want to do down there...)
The website with these images described the parade a "fluvial."
When I was in undergrad, the last night before coming home from college for christmas for the first time, I painted my whole body with pthalo blue acrylic and chained myself to a rendition of the golden gate bridge. Yes, naked. And blue.
