Reason to watch: If you are around age 12, and have a crush on either Alex or Nat Wolff, and you got your parents to shell out at least $25 for a ticket to see “Nat and Alex Wolff: Fully Clothed Tour.” (The show and concert have different names, in part because this is not a show tour.)

What’s new: Plenty, most notably that “The Naked Brothers Band” — a mockumentary-style show about an adolescent pop group led by the Wolff Brothers — is no longer an actual TV series, but a handful of stand-alone “movies” (or one-hour episodes) and three holiday specials, including one that’s animated. Nick is still calling this a “third season” of the series, but that’s a bit of a stretch because, in effect, fans will have to wait three or four weeks between originals. The second season, which ended in April, actually was made up of 10 weekly half-hours, so the third season — which launched Oct. 18 with “Mystery Girl” — will actually have more total on-air time.

Why is Nick doing this? Would you like my hunch? To boost fan interest in so-called “event” programs. “Mystery,” with “iCarly’s” Miranda Cosgrove, was seen by 4 million viewers, which is a very big figure for Nick and the show. The next “movie/episode,” “Operation Mojo,” airs Nov. 22, and the first animated special, “Supertastic 6,” debuts Nov. 26.

OK, what else is new? Besides the first-ever tour, there will be 13 new songs this season, and more celeb cameos, including Whoopi Goldberg, Natasha Bedingfield, David Attell and a lot of musicians like David Desrosiers of Simple Plan.

Bottom line: If you’re the aforementioned 12-year-old, you need no reason to love “NBB” any more or any less this season. This bottom line, then, is for bemused or confused parents. The best way to approach “NBB” — the show and the band — is with an air of determined nonchalance, along with a sense of “this, too, shall pass.” And it shall. The pop songs may be bubble gum, and the production values somewhere between “straight to DVD” and “home movie” — remember that “NBB” is supposed to be a mockumentary — but “NBB” is also part of a TV tradition that stretches all the way back to “The Monkees.” And, guess what? You survived.

But the boys — particularly 13-year-old Nat — are not without talent or charm, while the rest of the band/cast members (Thomas Batuello, David Levi, Qaasim Middleton and, of course, Rosalina, played by Allie DiMeco) are nice on-screen foils and competent backups. In other words, your kids could do a lot worse.
