Rockkroc runs repeatedly back and forth patrolling an entire area if the Stop & Go Barrels are on the "GO" setting. When Donkey or Diddy touch it, the either lead monkey is injured and then runs away. Rockkroc is dormant when the Stop & Go Barrel is activated to switch to the "STOP" setting. While it's dormant, it is unable to attack Donkey or Diddy, not even when it curls in a boulder. The "STOP" setting is only temporary and switches quickly switches back to the "GO" setting.
Rockkroc can only be defeated from Donkey's handslap attack in the Super Famicom or Japanese version of Donkey Kong Country if it's dormant during the "STOP" setting on the Stop & Go Barrel. This technique is also effective in the Game Boy Advance remake of Donkey Kong Country. This move may cause Rockkroc to drop banana(s) or an Extra Life Balloon behind.
