She is a kind giant. Secondly,Glumdalclitch on the other hand has no such fears, she is a child amused by a new toy. She comforts him and looks after him as a toy. Thus, he finds security in the company of the little girl as he is in world where his life is threatened. Gulliver fondly names her "little nurse" (Glumdalclitch), and she names him "gildrig" meaning mannequin. She remains his nurse after he is taken to the court and saves him from dangers.
