Designed by German engineer Wernher von Braun, Fred's Crocs are the most highly advanced pieces of technology ever invented. It is said that if Royal Air-Force pilot Ace Airman didn't retrieve them from under Hitlers bed during a sleepover in 1945, the Second World War would have been lost.

Fred's Crocs are currently protected by over 42 international treaties as, if the right tap-dance sequence is bashed out, the entire world (including Croydon) will explode.

As you can see Freds Crocs are permanently locked in a 'handle forward' stance, this is so he cannot outrun any bears that may be chasing him and Frankie.

Fred's Crocs represent Man, while Frankie's Crocs represent nature.
