Ntxiv nrog rau lawv lub luag haujlwm tseem ceeb hauv kev tsim kho, kev tsheb ciav hlau khiav spikes nrhiav kev siv hauv kev kho tsheb ciav hlau. Thaum hnav los yog puas lawm, spikes yuav raug hloov los tuav txoj kev ruaj ntseg thiab kev nyab xeeb. Kev txhim kho kom raug thiab kev saib xyuas ntawm cov kab sib txuas yog qhov tseem ceeb rau tag nrho kev ntseeg siab thiab kev ua haujlwm ntev ntawm kev tsheb ciav hlau, hais txog lawv qhov tseem ceeb hauv kev ua haujlwm tsis sib haum xeeb ntawm kev tsheb ciav hlau thoob ntiaj teb.
