Winner of the 2020 Theodor Seuss Geisel Award for most distinguished American book for beginning readers.

In this very young picture book mystery, a little boy out for a walk with his family stops to show a building doorman his new "bot": "I have a bot!" Only he doesn't have it for long, because it floats up out of his hands like an escaped balloon. "Stop! Bot!" Springing to action, the kind doorman runs up to each floor of the building to try and catch it -- along with the help of each floor's resident. But while everything looks normal at first, every floor (and resident) is a little more wacky and unusual than the last! Musicians, baseball players, zoo animals, and finally a very large monkey all play a part -- but will they rescue the Bot before it's too late?! Children will love all the funny details and easy-to-read words in this very playful picture book!
