Granny and Dribbles from the show Harlem Globe Trotters (1970) were briefly seen inside the Globetrotters bus (Granny was driving and Dribbles was sitting in the back) when the Globetrotters follow the Mystery Machine to Picnic Island. The presence of Granny and Dribbles were never acknowledged by the Globetrotters nor did they interact with the two characters. The same goes for the Mystery Machine gang. Both Granny and Dribbles did not tag along with the Globetrotters to Haunted Island for reasons unknown.
