When Wendy, Marvin, and Wonder Dog find evidence that entire rocks and trees are somehow moving during a bike ride through nature, they report their findings to the Super Friends, who are somewhat more concerned with a recent wave of thefts of large industrial air conditioning units. But are the two events connected? A house near where Wendy and Marvin were is occupied by Mr. and Mrs. Mole, who don’t welcome the attention of the Super Friends…mainly because they’ve found a path to an entire underground world full of walking rocks and trees – and diamonds worth a fortune. But the caves are hot – hence the stolen air conditioners. When the Super Friends try to confront the Moles, the ensuing battle depends on whose commands the rocks and trees obey.
