The Magic School Bus Rides Again

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".

A field trip to the world's windiest mountain helps Keesha and the class strengthen a set piece for a sequel to "The Three Little Pigs".

Ms. Frizzle takes the class to Hawaii where an overprotecting Wanda gets schooled when she's forced to think like a tiny little fish.

Tim pens an original comic book for the school's upcoming time capsule ceremony that pits Weatherman against Captain Rock Man. But who will win?

While visiting a mountain made of magnetite, Ralphie and the class shrink to subatomic size to get some hot tips for their disorganized dance troupe.

Carlos plans to convince the principal to let the students keep a pet rat in the classroom. But first, he'll have to stop sneezing.

When the class gets an invite to compete on Tim's favorite TV game show, the bus takes them all back in time to bone up on how fossils are formed.

From scratch marks to stolen pepperoni slices, the science classroom's a mess -- and all clues seem to point to Wanda's bird friend, Marty the Magpie.

Wanda's been so busy planning this year's Fall Fun Feast that she forgot about the food. Now her only hope is a farm that's supposedly haunted. Gulp!

Ms. Frizzle and the class race across the internet to recover a digitized Arnold before Jyoti's grandmother accidentally deletes him.

The kids learn to see the world through the eyes of different animals when a careless Arnold loses Carlos's pet rat -- then turns her invisible!

While building (and rebuilding) their own space rover to tackle the terrain on a faraway planet, Jyoti and the class learn that it's OK to fail.
