This story is a sequel to The Prisoner of Zebra
It was supposed to be a routine visit to Ponyville-- as if there's anything such as 'routine' for Lieutenant Flash Sentry (HERO OF EQUESTRIA). But, as always, things soon take a turn for the worse as Sentry finds himself facing stunning news-- as well as yet another ridiculously dangerous mission in a strange and exotic land. Only this time, how will he fare without the help of Special Agent Golden Harvest?
Volume 6 of the Flash Sentry Papers.
