Imifino nezithelo ezisemgudwini wamanzi ziyahlakazwa, zigingqike, zihlanzwe futhi zilethwe ngaphansi kwamanzi anomfutho ophezulu namabhamuza anamandla. Isihlabathi siyokwehlela esitokisini sokuhlukanisa esingezansi futhi ngeke sibangele ukungcola futhi. Imfucumfucu nezikelemu ezisemanzini ziyoqoqwa ngenetha. Futhi i-roller yebhulashi ingahlanza imicu, izinwele, nokunye. Bese imifino nezithelo ezihlanziwe ziyophinde zihlanzwe ngokufafaza.
