The name Hasselfrog comes from the common proverb "Hasselfrog bog", referring to vandalism. Hasselfrog's parents were Christina and Bobby Hasselfrog. Christina was of a Norwegian heritage, while Bobby was of the Froggian race. Froggia is a tiny city in Sydney, which has the unique Froggian species of human. This refers to the fact that all the Froggians had been ugly and green-coloured, as if they were suffering gangrene. Thankfully, this was just a human race.
