Theo is constantly amazed by everything he sees at Sheffield Children’s especially the amazing bravery of the girls and boys who are being treated. Theo keeps them entertained, telling stories of his wild adventures around the world and demonstrating his circus skills, like juggling and dancing. Sometimes Theo takes a tumble and bumps his head or hurts his arm, but the doctors and nurses are always on hand to help him get better.

Each night, Theo goes to sleep in his very own hospital bed in a very quiet corner of Sheffield Children’s, where he dreams of all the adventures he has had, and those which are yet to come. Theo is an active fundraiser and you will see him doing lots of different things from running, cycling and jumping out of planes to taking part in physiotherapy, joining in with doctors and nurses to having an X-ray.

Theo made a very special appearance as his own sculpture during the 2021 Bears of Sheffield sculpture trail. Designed and painted by TADO, who created the iconic and beloved mascot in 2014, Theo's sculpture now lives outside Outpatients at Sheffield Children's.
