Season of the Skull is the 29th episode of the series.
Plot
In hot pursuit of the Dark One Worm, the Super Robot is mysteriously transported to a strange village where everything is, as Otto puts it, "spook-tacular." The citizens turn to the Monkey Team for help, claiming that they are plagued by a curse that is taking away their little ones. What secrets these strange people are really hiding will surprise them.
