When animals are going missing in their town Gemma, Ned and Matt investigate to find out what is going on. Matt's cat Boots has gone missing and so they check out the park where there is a strange noise coming from the water. When the children use a frozen chicken on a rod as bait they are amazed to see what happens, the chicken is taken by a crocodile, what on earth should they do now?
