As we near the end of Microbe Theater, we get to see what our animated friends look like in real life.
By the way, in this episode they refer to "Tadayasu" several times. Tadayasu is the main, human character in the original Japanese anime story "Moyasimon: Tales of Agriculture" that Microbe Theater is a sub part of. Tadayasu's special ability is that he can see and interact with microbes.
