Kari was like a baby. What are the main points of comparison.

The author has compared Kari with a baby because his call was more like that of a baby than an elephant. He had to be trained to behave well. If he was not told when he was naughty, he did more mischief. He understood words like children do. He was trained to sit down, walk slow and fast just like a child is taught to sit and walk.
