That would be the Pokemon Claim thread. Digi was making a joke, which is why his post was struck out like that.
bloodex - Cause mythical creature+ are more awesome!!
There's still no need for it. For the claim threads that we do have, those make sense because they're something that the majority of people have an interest in. Pokemon, celebrities, songs, anime/manga/game pairings... There's fun with those because they're something that pretty much everyone has an interest in (even if said interest doesn't extend to claiming them, people still talk about them). With mythical creatures, how many people actually do know more than the common ones? There's not a big draw for the claim thread to be made. (I haven't even seen any discussion threads/user groups/fan clubs about mythical creatures.)
i think there is tv shows not sure. i dont claim, i dont get it.
None for TV shows currently. There's: Pokemon, song, celebrity, and bishies. There used to be a thread for claiming a "series", which is why there's a space for it on the profile page, but in looking over both Other Entertainment and Japanese Entertainment (and even Video Gaming) I couldn't see it.
And claiming is just something that people do for fun on here to show their devotion to their favorite things.
But for mythical creatures, I don't see much interest for it, so... Like I said, though, you could have fun with it still and create a user group/club to gather other mythical creatures fans and pretend to claim creatures. It won't be officially added to the profile page, but you could still do it that way.
