Tornadoe Troop On Lemur Street, we have been introduced by two seperate lemur families, the Graveyard Gang and the Tornadoe Troop. These two groups have lived in the areas of Madagascar for generations to come through rivalry. Ring -tailed lemurs are actaully the most aggressive and territorial of of all their lemur cussons. Exertions from other troops often results in fights, concerning territory and all its resources.
