Alison comes to the rescue of two pet trade marmosets; both of which have celebrity names. Chuck Norris is first to be collected from a flat in central London and then Alison heads to High Wycombe to collect Sid Vicious, it’s hoped these marmosets can live together when they get back to the park. The primate care staff try and make every day interesting for the primates; at the spider monkey enclosure Toby is using hidden treats to get his lethargic charges working for their breakfast, and Cat tries to find a way for the golden cheeked gibbons to keep cool.
