I'll be honest and say the theme tune is what got me to watch this cartoon.
I know it used to remind me of Dogtanian, maybe it was all the anthropomorphic animals. As the previous reviewer states, it is the Philias Fog story retold, 'Willy' is an English gentlelion who accepts the wager that he can traverse the globe in 80 days. To do this he uses all sorts of modes of transport, including, hot air balloon, elephant, train, camel etc, etc. All the while being sabotaged by the minion of the guy who bet him he couldn't make it in 80 days.
Along with Ulysses 31, Dogtanian, Raggy Dolls, Mysterious Cities of Gold and later in my childhood - Fantastic Max, the pinnicle of cartoon theme tunes was reached.
