Little Huey was sent to steal the Transmogrifier from the Meridian Mind Institute, so that his own mind could be switched with that of the wealthy Premier of Vadeem. On the cab ride back, he stopped for a time at a pizzeria, leaving the Transmogrifier in the back seat. When he returned, the cab had vanished along with the device.
Little Huey was able to identify the same cab (although he did not notice that the cabbie Oscar was now a Turtle), allowing Mr. Big to reclaim the Transmogrifier. The two gangsters kidnapped the Premier of Vadeem, but when they turned on Oscar, he defeated them easily and made off with the Premier.
Little Huey drove in the car chase that ensued, which led to a four-way crash. He was left in the crashed car for the police, and was presumably arrested.
