A Garland of Toddlers

The kindergarten teacher took the toddlers out for a walk, and so they wouldn't get lost, she told them to hold on to a string. But as soon as the teacher got distracted for a moment, the string with the toddlers disappeared... Where to look for them now? And while the teacher was searching for the children, they were having a great time at the zoo. And this turned into a very funny story... For preschool age.
