S01E01 Frizzle of the Future
Change is good for everyone except Arnold, who's worried that a new teacher - Ms. Frizzle's young sister - will alter the class's "ecosystem".
The class constructs a giant robot with help from brainy scientist Dr. Sarah Bellum, then takes a look inside Ralphie's nervous system.
Ms. Frizzle's sister takes her class on a slew of wild science adventures in this update of the beloved animated show.
