St. Valentine's Day Mass Production / V for Valentinedetta!.It's the day before Valentine's day, and Keroro, inspired by the sales of chocolate on this occasion, plans on cashing in by manufacturing and selling traditional ikinari dango or sweet potato snacks, as a substitute for traditional Valentine's Day chocolate. Unfortunately, all the marketing and promotional power of the Keroro platoon fail to overturn international tradition, and Keroro is left with stacks and stacks of ikinari dango that will haunt him for many episodes to come. Valentine's Day arrives at last, and whether it be chocolate handmade from store-bought ingredients or coca flown from Ghana by the Nishizawa Peach Group, Natsumi and Momoka are on a sacred mission to give their chocolates to the men in their lives (Saburo and Fuyuki respectively), but each has her own obstacles to overcome - Natsumi's own nerves get the better of her at each turn, and Momoka watches helpless as Fuyuki receives Valentine's Day chocolate from other girls (Fuyuki himself has a different sort of problem, in the form of the combined jealousy of the menfolk of Kisshou Gakuen.)
