When Nature Calls is the sequel to the first Ventura series, starring a returning Jim Carrey as the title character, this time around, the pet detective is tasked to find the sacred animal that has disappeared from a tribe before war breaks. One thing that is changed here is that the humor is more crude than before, which sometimes works and sometimes doesn't. Jim Carrey also lets loose with his craziness and weird actions, which again, sometimes works and sometimes doesn't. There are a few scenes which are comedy gold however and on the whole, the film is enjoyable. The plot is simple but has enough happening to keep the film going. Ace will travel into the jungle, get into trouble with the local tribes while trying to track down the thief. Even at only 1.5 hours long, there were numerous scenes which seem pointless and bloat the film up, almost as if the editor didn't what to do with those extra scenes and decided to put it in anyway.
