Another fantastic magical dino-tastic adventure series from CBeebies superstar Andy Day, and illustration powerhouse Steven Lenton!

Hello! It's me, Ruby Thumb. You might remember me and my dad - we're famous POOPAs. What do you mean you've not heard of us? And you don't know what a POOPA is?! It means we're Protector Of Our Dinosaur Allies - obviously!

Me and my dad have loads of amazing adventures in Dinotropolis - an incredible island, full of dinosaurs who live just like us humans do. And when we go there using our special magic Ammonite shell, we turn into dinosaurs too!

I can't wait to tell you all about our amazing frozen adventure. We had to rescue a baby woolly mammoth, and make sure it got back safely to its mummy - as well as un-freeze Dinotropolis! It was pretty roarsome - let me tell you all about it!
