The most effective way to counter the Zombie Hamsterball is to use the Spear-mint, which creates five Spikerocks, therefore quickly nullifying the threat. Spikeweeds can also be used for their cheaper price and just as fast recharge, although they will only take one roll. This, however, will not work if the Zombie Hamsterball approaches the Spikerock using a slider tile. A Spikerock can instantly destroy it, but it will degrade it once.
