Danny, the Angry Lion (Hardcover, Turtleback School & Library ed.)

Danny wanted sausages and raspberry juice for lunch, but his mother only gave him beans and potatoes. Danny hissed and angrily pushed his plate away. A wild and dangerous gleam shone in his eyes. Danny donned his lion suit, sharpened his claws, and set out on the prowl, determined to devour anything and anyone he got his paws on!

A series of surprising encounters takes the edge off Danny's appetite -- and his anger -- as Danny discovers how being friendly can turn the blackest mood bright.
