It's been nearly three years since Netflix said they'd be making a reboot of '90s kids' favorite educational cartoon, The Magic School Bus. The remake of the 1994 hit series was expected to debut in 2016.

Earth to Netflix: It's now 2017 – and we're still waiting to go on a science trip in the flying school bus with Ms. Frizzle and her class. So where the heck are the new episodes we were promised?

Netflix hasn't given any new information about The Magic School Bus since 2014. But one of the show's producers, Stu Stone, (who was also the voice of Ralphie Tennelli in the original) has shared a couple updates.

And it turns out we may have to wait a bit longer, because Stone told TMZ that production of the show just started.

On the bright side, he added that Netflix is putting a lot of money and effort into it. Netflix's chief content officer told The New York Times in 2014 that the revival will include 26 half-hour episodes, featuring computer-generated animation and an updated school bus equipped with modern technology.

And like the original, it will feature some celebrity cameos.

"There are tons of cameos planned. I know that there are big stars who want to be involved in this," Stone told TMZ. "And there's a whole generation of people who grew up on this series that want to be a part of it now that it's back."

The date of the reboot is still unknown – but you can watch the original series on Netflix in the meantime.
