Digdogger

Digdogger in The Legend of Zelda
The Digdogger in this game is one of the easiest to defeat. Using the Recorder, play it to smash the Digdogger into three smaller Digdoggers. Play the recorder again, and the creature will become paralyzed. Use the sword to defeat the smaller versions with ease, then grab the fifth piece of the Triforce.

Digdogger in Oracle of Seasons
The Digdogger in this game is defeated in an entirely different fashion from it's predecessor. Using the Magnetic Gloves at north polarity, you can cause the spiked ball that lay in the boss area to smash right into Digdogger. After a few smashes from the spiked ball, the Digdogger will split into it's smaller versions. Hit each of them with the spiked ball or sword to win the Nurturing Warmth, the fifth Essence of Nature.
