Nhanganyaya: Mhuka dzisina mahwanda
Mahwanda akaoma, ane nyanga, uye anodzivirira patsoka dzedzimwe mhuka. Vanopa rubatsiro uye vanobatsira mhuka kufamba-famba munzvimbo dzakasiyana-siyana. Zvisinei, hadzisi mhuka dzose dzine mahwanda. Muchokwadi, kune marudzi mazhinji akasiyana emhuka aripo asina zvimiro izvi. Munyaya ino, tichaongorora kusiyana-siyana kwemhuka dzisina mahwanda uye tokurukura mamwe emamwe magadzirirwo akasiyana akagadzirwa nezvisikwa izvi.
Mhuka dzisina Hooves

Mhedziso: Kusiyana kweMhuka dzisina Hooves
Mukupedzisa, kune mhando dzakawanda dzemhuka dzisina mahwanda. Kubva kumhuka dzinoyamwisa kusvika kumollusks, boka rega rega rakagadzira zvigadziriso zvakasiyana kuti zvivabatsire kufamba uye kurarama munzvimbo dzavari. Kunyange zvazvo mahwanda achibatsira dzimwe mhuka, kusiyana-siyana kwemhuka dzisina mahwanda kunoratidza kuti kune nzira dzakawanda dzokufamba nadzo mumhuka.
