It's been bugging me for awhile now. So i have a bunch of these ****ty stones that are round and purple with popo face on this and dont know what to do with them. Can someone explain? I wanna get rid of them cause i havent used one since i started playing.

You use them to revive dead teammates.

The Popo Stones that are a full head, like a head with 2 eyes and a mouth, those are to revive team mates, the ones with well, a small head and a neck (or torso?) I don't know what those do, and a Popo Stones with half a face, it looks like a moon head, those you can revive yourself with, but are obtained from events I believe.

the ones with neck is to teleport back to you respawn point.

got it, got it and got it! Man you guys are so helpful. This website really is something, thnaks! :P

Haha and the funny thing is i have like 30 of these and everytime i partied up i couldve revived a buddy, what a shame i was lacking the knowledge of this stone!
