Spinies R can sometimes cause the DEF Down status ailment if they harm Mario. One of their attacks involves a group of them jumping before attacking while the others remain stationary. Mario must move around and jump over the Spinies R that were stationary before the attack. Otherwise, the jumping Spiny R will damage Mario. An alternative attack involves a Spiny R marching towards Mario, with some others following. Mario must hit the lead Spiny R with his hammer and hit it again when all of the following Spinies R line up with each other. If the player does not hit one or more Spinies R, they will hide in their shell and damage Mario with their spikes. This process can be repeated one or more times depending on the number of Spinies R on the battlefield. Using a hammer causes the Spinies R to flip over, allowing Mario to jump on them to deal critical damage.
