Join Felix and his grumpy cat Gary in this humorous story about a child's endless imagination. Felix loves playing in his garden, but he's always avoided the stinky compost bin fearing that it's home to Mulchy the Monster. One day, determined to take back his garden, Felix musters up some courage and approaches the smelly heap. But instead of a monster, Felix finds... an egg! What could be inside? An alien? A dragon? What if it's a baby brother?! As he imagines all the possibilities, perhaps can Felix learn to share his garden after all.
