Circuit breakers are not intended to protect motors. They are there to protect the wiring. You can burn up a Fisher Price motor at relatively low current if you run it at low speed under a moderate load for enough time. You can also run a Fisher Price motor at high current for a long time if it's spinning fast enough for its internal fan to be effective.
