Because its special ability is pickup allowing it to sometimes pickup an item.
It is a sirvice that has changed over the generations of Pokemon games. In Gold, Silver, and Crystal, you could use it to transfer items between two people. In ruby, sapphire, and emerald (and every game henceforth), it has been used to receive Pokemon given out at events, beginning in the USA with a shiny Zigzagoon given out as a promotion.
I use a Zigzagoon the higher the lv the better items it will pick up.
Well, it's useful if you have a Pokemon like zigzagoon or linoon with the ability pickup. :)
You can only breed pokemon, not items. Items aren't alive!
dont care
there are a few items , but the Pokemon SMEARGLE is inside
Get a Pokemon like zigzagoon and just walk around. Make sure it is not holding any items. Then when you walk around, check your pets holding items after about 30 SECS, and there should be an item there :)
You can't duplicate items unless you use a gameshark
you can't get jirachi in emerald, only by Nintendo events, they give out special items that helps you get rare Pokemon.
click on the pokeball in front of you and it should be an item
Some of them contain items.
YES, duplicating Pokemon and items, going to moon etc
