The tiger is sleeping at the bottom of the pit, so direct interaction with it is not part of the puzzle. The woman repeatedly states 'It's not high enough' until the ladder is complete, indicating the need to continue adding rungs.
Look for interactive elements in the environment that can be used as ladder rungs. Pay attention to the rescuers' actions, as they provide additional ways to extend the ladder or create footholds. The puzzle is completed when the woman can climb out and says 'Thank you'.
