Every Friday Evening

Would a trip to Mars cure a velociraptor's allergies? Molly, Patrick's baby-sitter, would say a triple-chocolate peanut butter brownie could cure them just as well. But the velociraptor wants to go to Mars and needs Patrick's help getting there. Patrick thinks that's no problem, until a spaceship carrying the Martian Imperial Army, the Martian National Peace-Keeping Force and the Martian Combat Reserve lands in his backyard. For Molly it's just another Friday evening at Patrick's house.
