Warning! This episode is all about the fascinating and gross world of doo doo.

We know you have a lot of poo questions because you’ve sent many, many of them to us. So we’re finally bringing you the poo answers! It’s a poop party!

We’ve invited scientists to tell us about weird animal feces. (It’s true! Wombats have cube-shaped poop!)

We tune into a news channel all about dookie (see Bristol Chart here)

We hear from our favorite “poo-tuber” Taylor the Turd about how some poops are helping fight serious illnesses. (Remember Taylor? Here’s her first appearance!)

Plus, a sorta stinky Mystery Sound and a Moment of Um answering a question: why is pee yellow?
