HA-HEE-HOO-HEH-HOH! Thanks to this invention made by yours truly—The Great Baikinman—we can shrink ourselves to enter a human's body! HAHAHA! "Hahihuheho", Baikinman's unique chuckle.

This is my first time visiting the insides of a human body!

Those are the red blood cells responsible for transporting oxygen. Seems like they're lost.

They look kinda derpy too. Maybe the owner of this body has no sense of direction?

Is it true that the white blood cells eat us bacteria?

HA-HEE-HOO-HEH-HOH! Oh, we're safe as a blockhouse inside this machine!

Oh yes, you're right! Hahaha!

There is no way a white blood cell can eat my machine!
