Amphibia chronicles the adventures of three best friends who find themselves magically transported to the world of Amphibia, a wild marshland tropical island full of anthropomorphic amphibians and dangerous beasts. The three girls are separated when they arrive in Amphibia, and Marcy finds herself living in the Newt controlled city of Newtopia. Science-minded, she uses her journal to catalogue and record the flora, fauna, and culture of the fantasy creatures in this new world.

This faithful recreation of Marcy's journal chronicles her adventures in the magical world of Amphibia. Packed to the brim with new character insights, world-building lore, and untold stories, this book is a must-own for any Amphibia fan!
