Only two Genkotsu appear in the twelfth and final level of Super Mario Land, World 4-3. They behave in a similar way to Piranha Plants, only they move quicker and are immune to the Sky Pop's missiles. They behave as a group - when one fist goes back into a pipe the other will come out shortly after, making it difficult for Mario to get past them.
In the second playthrough, a third Genkotsu appears in the first pipe to the left in front of the 18 coins.
