Namekian Dragon Ball

From Dragon Ball Wiki, the ''Dragon Ball'' encyclopedia

The Namekian Dragon Balls are a set of Dragon Balls created by Guru. These Dragon Balls are similar to the ones on Earth in powers and appearance, however the Namek ones are as large as volleyballs. There are also two extra precautions taken on the Namekian Dragon Balls; the summoner is required to utter a Namekian password in order to summon the Dragon God, Porunga. The other precaution is that the wishes must be spoken in the Namekian language. Once Porunga is summoned, he has the ability to grant three wishes, that are somewhat less powerful than Shenron's wishes. For example, Porunga could only revive one person at a time while Shenron could revive an infinite number of people at a time (though he was eventually modified to do mass revivals after the Frieza Saga), but Porunga can grant the same wish as many times as the summoner pleases. The time the Namekian Dragon Balls take to restore is 130 days, not like the 365 days required for the Dragon Balls on Earth, this is because a year for the planet Namek lasts only 130 days.
