# Grossology (TV series)

Grossology (also known as Glurp Attack in Quebec) is a Canadian animated action-adventure television series produced by Nelvana and based loosely on the non-fictional children's book series of the same name by Sylvia Branzei.
The show first premiered on YTV in Canada on September 29, 2006. The original run ended on October 24, 2009.

## Premise

Ty and Abby are a teenage brother-and-sister crime-fighting team who report to the Bureau of Grossology, a secret government agency whose job is to investigate gross criminals, their gross crimes, and/or various gross phenomena. Each episode of the series follows the pair on adventures based on real scientific facts. Aided by their friend Lab Rat (a tech specialist and a lab researcher), their boss The Director, and their police liaison, The Detective, Ty and Abby work to keep the city safe, all while keeping their identities hidden.

## Reception

Grossology received slightly positive reviews from critics and audiences.
Emily Ashby of Common Sense Media gave the show rate three stars out of five, stating that "such topics offer ample breeding ground for jokes as well," and "nearly as entertaining […] but rest assured that, while they're laughing, they'll be learning about science ... or at least it's yuckier side."
