Group Role: Cassie is the Animorphs 'Animal Expert'. She basically knows where and when to use the right morph. With her mom working at the 'Gardens' she has access to all the exotic animals, which allow her and the Animorphs in acquiring dangerous battle morphs. She also has many other animals in barn, which in fact is basically a Rehab Clinic for injured animals. What's a better place for acquiring more morphs?

Cassie is also the peace keeper of the group. She knows the right thing to say at the right time. She's very good at stopping fights and arguments amongst the Animorphs. From time to time she also brings up morals and issues which help the Animorphs stay 'civilized' while they continue fighting their war against the Yeerks.
