They attack by throwing boulders at Mario and Luigi. This attack can be countered by a jump. If they get dirt on their faces, they miss and throw it above the bros., which can hurt Mario and Luigi if they jump. The moles may also "wink," showing which bro. they are attacking. This attack can be countered with the hammer, which can be done several times until the mole jumps over the selected bro. to fall on him.
The second set of numbers next to the enemy's HP, POW, DEF, SPEED and Coins are stat increases from the Challenge Medal accessory; a 50% increase for HP, DEF, SPEED and Coins earned, and a 150% increase for POW.
