What does Halloween mean to a mouse who has never celebrated it before? Imagine Happy’s fright when the nextdoor neighbour hangs a ghost on her house. Witness his displeasure at the thought of dressing up and walking door to door to beg for treats. What a nuisance! What are treats anyway? Then, see the transition in the sweets-loving mouse when he learns that treats mean candy, his favourite thing. Suddenly, Happy can’t get out the door fast enough. But John needs a costume, and the only face paint they can find is shoe polish. How can Happy get John ready to hit the streets before the kids take all the candy? And what sort of costume will the little mouse wear? And what happens if you eat too much candy, anyway? Join John and Happy as John introduces Happy to his very first Halloween.
