Any class can ride this mount.
You need to complete guild quest lvl 7 - mage tower mission
Edit: source said mount can’t be mounted by all classes, weird, I’m gonna check Ktos infos then.
Edit 2: got a reply from Ktos thread, Ktos made guinea pig available for all class when Penguin arrived.
Is this legit?
Seems legit.
But also not.
Poor little guy…
sorry but she is too cute for me to pay attention to anything else :3
what were we typing about?_?
Well, it’s really cute.
Awesome though, gtz to the guild and owner. (if true)
I have to correct you guys, Kuroi got the first guinea adult pig mount on itos Klaipeda Server.
I got it 4 hours before Lunar 
Looks like you want a cookie…
Master Kuroi is correct, Lunar may be the first mounted class to have a guinea pig, but the first guinea pig to not die was indeed “Cute Hammy”, who was raised by the entirety of Crimson Guild, notably Uncle Wizlert and Master Kuroi.
In our pursuit of cute hamsters, we lost two poor souls at the hands of IMCs incompetence and maintenances. Princess Lindely’s guinea pig was struck down by overfeeding and possible visual bugs, while Uncle Wizlert’s pig met its demise through unspeakable means.
Our third child made it through the arduous 5 day journey to adulthood, but due to even more IMC incompetence, the life expectancy appears to be 45 days unlike kToS. In the meantime, we will continue to fail to be able to enter the guild mission on 99% of our members, but we will continue to try to add more members to our guinea pig family.
Can confirm.My good friend Lunar has been keeping me updated on it’s progress and I’m glad to see it made it through alive!
Mine’s the second one xD Kuroi got the first one ;-; By 4 hours only tho ~
A sad state of game when the only thing you can brag about is some mount. Thanks for cringe.
Oh what a cute little sweety 
is it a boy or a girl?
At least it was an in-game accomplishment, not a dumb lockbox opening; that would be truely cringe worthy.
Well, the person who got it didn’t even make this topic - this isn’t really bragging. 
@Kuroi
All right, I will change my title.
@Vheissu
Aww, poor things 
@2015huehue
This is not bragging. Any other guinea pig owner can come here and share that happy event.
I would rather prefer the community of this forum post happy stuffs about the game they found rather than just complaining or post off topics trolls.
I wish the forum to be happy not to turn into toxic community. So I’m going to conitune post happy/nice stuff.
Anyway, gratz to all who were able to raise one
lmfao stfu. If this forum isn’t filled with IMC hate and ENDLESS bitching then it’s “cringeworthy”? Please, uninstall your computer.
WTF is that girl doing to the poor pig ><
Hope nothing happens to the poor cavy
