"The inflatable genius of Gerri Poveri is about to rise to the surface."
~ - Gerri Poveri

Gerri Poveri is a corrupt journalist featured in the Magic School Bus episode "Ups and Downs". In order to boost the ratings of her tabloid talk show In Your Face, she fakes a monster in Walker Lake. Ms. Frizzle and her class travel to the bottom of the lake to see the monster, but discover it's just a giant inflatable plesiosaur. They then expose the hoax to the public and Gerri Poveri is forced to apologize on her own show. It was revealed after she apologized, she got a starring role in a new underwater action-adventure series. (Though the name of the show was never mentioned.) 

Gerri Poveri was voiced by guest star Cindy Williams.
