I'm level 49 now and it is not in my hot topics...

it is new. less than 7 days... But that should be included in the description for these events

lol you are right. I:dizzy: spun the wheel about 500 times already and no Tenten still...

Yes, which is why i spun the wheel. I could care less about Tenten honestly but I was just agreeing and stating the fact that i havn't gotten her yet at that many spins yet.
