Fan Casting The Monsters in Ddotty and Sleepground: A needlessly touching story

A group of monsters, consisting of a large number of zombies, skeletons, zombie villagers, and a small number of zombie pigmen, invade the village where Old Mr. Ddotty lives. They kidnap Heptagram, who came to visit his grandfather's house. (Since they appears as a group in the story, I thought about using more than two or three voice actors.)
