Jimmy Z is insecure, hesitant and unsure – that is until he gets a video game console in his hands! And now this gamer gets to play with the Teleporter, Aviva’s particularly temperamental invention that delivers the team’s latest breakthroughs to the Kratt brothers. He also drives the mobile headquarters, the Tortuga HQ, as it flies from habitat to habitat around the world. It is also possible that he is a video game designer since in the episode A Bat in the Brownies he said he's going to create a video game where a bat has to catch misquitos. He is also a good cook and has a grandma named Jimmina who has yummy recipes. And he always seems so have a piece of pizza in his pocket everywhere he goes.
