In battle, she digs through the ground and surfaces out of one of two holes to throw various objects at Kirby. They include flaming oil drums (giving the Fire ability to Kirby), tires (giving Wheel), bombs (giving Bomb, obviously), spiked balls with sharp edges (which gives Cutter), and other menial things like rocks and screws. Every so often she will retreat to the background and out of Kirby's reach. While in the background, she may also try to jump into the air and dive onto Kirby. If she misses one of the holes and instead lands on the rocky ground, however, she will briefly be stunned before leaping into the nearest hole.
Mrs. Moley is a large female mole, and is the female counterpart of Moley. She greatly resembles Moley, and the only difference between the two is that Mrs. Moley has a pretty bouquet of pink flowers around the top of her head. In the middle of the flowers is a bright red poppy. She has broad yellow paws tipped with sharp red claws.
She is also shown to have a curly, pig-like tail and a marsupial-like pouch, both of which can be seen when she is fully visible and outside one of her holes.
- Whenever Mrs. Moley lands on the hard rocky floor in contrast to falling into one of the two holes on either side of the screen, Mrs. Moley will also take a small amount of damage along with being stunned.
- This also means that Mrs. Moley is the only boss in the Kirby series the player can defeat without attacking whatsoever, albeit very slowly.
