a. The Monster has no control over its shapeshifting whatsoever, because he doesn't understand it. In this case, how he always has two eyes and an appendage at a fixed position, the former having a fixed appearance, as well as always having a mouth-equivalent orifice seemingly at a fixed position when he appears to insert things into it is mighty odd.
