Hey, I have no problem with making a new cake every couple of weeks*, and you're right, Xeno can take care of the balloons. It'll be fine.
* Monday's Emporium does not guarantee the quality of the cakes. We are not responsible if the cake bites back. We are not responsible if the cake is made out of a different substance every time it is made. We are not responsible for any instances of the cake mugging you in a dark alley. Monday's Emporium acknowledges it is not a cake making company and therefore does not fully understand the dark rituals behind making a cake. Consumption of cake may lead to injury or even death. You must be 21 or over to consume the cake maybe, depending on what it is made of that particular week. Eat cake responsibly.
