How can you complete secret missions and make exciting things happening when you have to drag around a guest? Luckily, it turns out Cousin Amelia is the kind of cousin they like-the fun kind! She's just as great at coming up with cool games and clever sayings as Orville and Wilbur, and she even travels with her very own (fake) pet snake.
Riot Brother Rule #24 says kid who are fun can become Riot Brothers, even if they aren't brothers, so obviously Amelia is in... And together they take on all-new adventures- starting a robot car wash, finding a lost mummy, and solving some mysteries... like why the neighborhood bully is following them around wearing aftershave.
This new hardcover edition features an updated paper over board cover (with shiny mummy bandages), plus all the new Games, Rules, and Songs... not to mention instructions on how to do the super-secret Riot Brothers handshake, so you can join in!
