Hello, my family and I recently went to the zoo and saw a number of animals.  Please identify the animals in this summary and organize them in order of size.  My son's favorite animal is an elephant, and he saw an elephant in the grassland.  My wife caught a parakeet trying to eat our popcorn.  My daughter was scared by lion that she saw on the prairie.  I missed all of these animals and only saw a boa constrictor in an a cage.
