Journey to the Center of the Earth is an American science fiction Saturday-morning cartoon, consisting of 17 episodes, each running 30 minutes.
It appears to have taken the 1959 film, Journey to the Center of the Earth, as its starting point rather than Jules Verne's original 1864 novel; e.g., including the character of Count Sacknussem and Gertrude the duck.
Long ago, a lone explorer named Arne Sacknussem made a fantastic descent to the fabled lost kingdom of Atlantis at the Earth's core.
After many centuries, his trail was discovered: first by me, Professor Oliver Lindenbrook, my niece Cindy, student Alec McEwen, our guide Lars and his duck Gertrude.
And so, for us, began a desperate race to the Earth's core... to learn the secret of the way back.
