Why is it three?
Doctor Dolittle is going to go to Africa.
The doctor said, " I shall only be able to take you three ー with Jip, the dog; Dab-Dab, the duck; Gub-Gub, the pig; and the owl, Too-Too.
This is from a novel "The Story Of Doctor Dolittle". I wonder he will take four animals but he says three. Why is it three?
