2. Ubumpunga isikhunta has ngezinga eliphezulu of ukusakazwa. Isici yalesi sifo engadini sitrobheli wukuthi sezulu efudumele ngenkathi sigcina umswakama high kungalima--60% amajikijolo. I izilonda yakhula kakhulu senziwe iziza engadini lapho kabi afundwa nomoya kanye strawberry esekhulile isikhathi eside kwenye endaweni efanayo. Ukutheleleka kwenzeka ngokusebenzisa amahlamvu ezindala, ukhula kanye amajikijolo ezilimele. Phakathi izimpawu zesifo ibizwa ngokuthi ukwakheka kwamabala brown on amajikijolo, okuyinto kungabonwa grey enamathela Fluffy. Khona-ke, babune futhi zinyamalale.
