One day Mole caught a cold. He felt terrible, shivering and sneezing one minute, burning with fever and all stuffed up the next. As he snuggles into bed, he thinks about his dream of traveling the world, and before he knows it, that's just what he does! Strangely enough, Mole's cold symptoms are reflected in his journey through underground tunnels to the frigid North Pole, the sweltering desert, the tallest mountains where the air is think and dry, the deep jungle, so steamy and humid. By journey's end, Mole's cold is cured and he has discovered that there's no place like home -- especially when it's filled with good friends.
