Fonda's guess: something frozen? something frozen in blue ice? a blueberry popsicle? a blue reflection? something in a blue reflection? something reflecting in blue paint? on a blue airplane? too shiny for the VW. (There is one word that's relevant in all of Fonda's guess).
Fonda: relevant word: ummmm BLUE? G'ma Airplane: are you kidding? no And where are the rest of my loyal follower guessers?
Lisa's guess: A beluga whale in an aquarium with the camera flash reflecting off of the glass. (Nope, but that's creative).
