Team Umizoomi
Geo is Milli's little brother, voiced by Ethan Kempner in Seasons 1-3 and Josiah Sanchez in Season 5. 11 year old boy who zooms everywhere on his Super Skates. Geo wears a shape belt containing many different kinds of shapes and can create anything. Often, when Team Umizoomi is stuck and needs some type of vehicle to assist them, Geo will figure out what they need, and present a blueprint for the thing that needs to be built, and then interact with the child viewing the show to figure out which building supplies are needed to fill in the shape belt by singing Super Shapes!
