At least they reached it! Better than STILL being in space searching for it with Bulma walking around only on a black tank top and her panties raising the sexual tension to the roof, all this because they don't travel using any form of FTL just Namekian Magical Science!
[rant] I swear, this people have mastered the ability to compress and decompress complete objects, vehicles or buildings into small and portatile capsules without ruining the structural integrity of the mentioned items but don't have FTL Travel? Goku himself becomes the most advanced method of FTL in the whole frigging Setting, and we know how little he's interested in Science and SCIENCE! [/rant]
Now silly rant aside, being still in Namek is better than Being still in SPAAAAAAAAAAAAAAAAAAAAAACE.
