If Mario is wearing the Spike Shield badge, they will not extend their spears to poke him if he readies his hammer. Being stomped with Spike Shield also works, however, unlike Koopa Troopas, this will not flip them over. If Mario uses Super or Ultra Hammer to land the first strike outside of battle, their spikes will not extend either.
