Heavy-duty Magnetizer

The Heavy-duty Magnetizer is a treasure in Pikmin 2 that is actually a horseshoe magnet. It is found on the 4th sublevel of the Snagret Hole where it is held by an Armored Cannon Beetle Larva that falls from the sky. It is the 68th treasure on the List of Pikmin 2 treasures.

Captain Olimar's Journal
"I've had an upset stomach lately. I'm not old yet, but I'm not young anymore either. Maybe I should start doing a better job of looking after my health. Perhaps basking in this contraption's magnetic rays will make me stronger..."

Sales Pitch
"The most powerful magnetic force in the universe! The healing properties of magnetic fields relieve backaches, headaches, toothaches, and even dreaded spleenaches!"

Trivia

 * Both journals reference magnets being able to cure injuries. This has been a theory ever since approximately 2500 years ago.
 * This theory was proven correctly in 2008 by a group of scientists, four years after the release of Pikmin 2.
