Is it possible to get a figurine of Tetra and the the pirates in your second quest after the Forsaken Fortress?
Pretty sure the last time you can take a picture of Tetra is after you first meet Ganon in the Forsaken Fortress and you're whisked away to Hyrule Castle; where she's following you around a bit. Anything before that should work too.
Also, if you didn't get one of Helmaroc King before that... well... you can't get all the figurines.
If you ask me, it's easiest to get all of the get-them-anytime figurines (Windfall islands, monsters, some bosses) in the first game. Then, in the second, get the one-chance-only figurines, like Tetra, Cyclos, and Puppet Ganon.
Also, here's a useful tip. You can still get a pic of Gohdan (the Tower of Gods boss) while he's on the wall. :)
