It's exactly like the hint says. It really is a hotdog on the nightstand. It shows up before sex, so easier to pick out without the distractions. The "Bruce Lee" one is a little trickier. Darce has something about Bruce Lee in her room. She talks about it too, but I think in a different scene. In the scene where you are looking for the hidden render, focus on Bruce Lee, try to find something out of place. This one is actually one of the more clever ones. Again, not during sexual activity.
