 During the sequence in Africa when Tommy saves Katherine, after he  takes her to shore, Tommy was actually supposed to be attacked by a  crocodile. He would have been dragged into the water by his Power  Box backpack when the crocodile grabs it in its jaws, but he manages  to jam a nearby log into the animals mouth and swims to shore. When  the crocodile follows Tommy to shore, Katherine takes a blow torch  from her Power Box and fires a torch to scare the crocodile away.  The sequence was ultimately cut to keep the running time of the film  short. This is explains why there is a photo of Katherine holding a  flame thrower on the back of the back cover of the movies VHS and  DVD, but it isnt seen in the film.
