Friend in a Shell

Charlie has a new friend, Boris. 

Boris is super smart, even though all he can say is "Pfoooosht!". With a huge, shiny shell and waving eyestalks, Boris tends to scare people away. But all he really wants is for someone to scratch behind his head. 

Only Charlie is brave enough to be his friend. And then, disaster! News crews are swarming the park where Boris lives and the zoo wants to take him away as their prize exhibit.

Can Charlie keep Boris safe? And, what on Earth do you feed a giant snail?
