The game doesn't truly end when you take the boat. A cutscene plays, the credits roll, and then you come back and continue playing basically the same as usual. However there is some special dialogue before you take the boat and just afterwards, so you might choose to make the rounds with your bear friends before and after if you want to read it all. That's completely your choice, though—there's nothing gamechanging in that dialogue.
- When you come back you'll still be able to complete the storylines of any bears that aren't yet complete
- One of the bears' storylines only finishes after you take the boat. So if for personal reasons you wanted to finish helping everyone before taking the boat, that's not possible.
