Who was Toto?  How did he come to the author’s house?

Dear student,

Toto, the monkey: Toto was a beautiful, little monkey. He was with a tonga driver. Grandfather took pity on him and brought him home. He created a lot of mischiefs and brought so much trouble in the house. He tore clothes and disturbed other animals in grandfather's zoo. So grandfather had to give him back to the tonga-driver.

Regards.
