If anyone's wondering why Pampaku is partially faded? When Pampaku resides in Sandoku body, he can be seen as a ghost or spirit. Like how Yugi Muto is able to see Yami Yugi when wearing his Millennium Puzzle. Sandoku is capable of talking to Pampaku either outside his body in crinkly flesh, or his ghost form when Pampaku stays inside Sandoku.

Only special eyes like Ethan's can see Pampaku's ghost form, this form only exists within Sandoku's body, Sandoku is able to talk to Pampaku like this, but some would assume Sandoku is talking to himself or to some random object. Only this with enhanced vision such Ethan can see Pampaku's ghost form, their sister Michiru can see Pampaku's ghost form, but since she needs training with her vision, she can only see Pampaku's outline.
When Sandoku sleeps, Pampaku's able to talk to others, but only ghost like head of his can be seen. If tensions within Sandoku's body rises, he can be seen, but its a very frightening sight. Pampaku even manifests a ghost version of his head to either spook the other ragtags rogues, or to warn strangers who approach Sandoku when he's asleep or blacked out. Pampaku loses this ghost form when he leaves Sandoku's body. Ethan was able to see this ghost form when he was attacked by Zazzy, Ethan is the main one who can talk to Pampaku's ghost form whereas others he either reveals himself in the crinkly flesh, or through Sandoku when he takes over. Pampaku can also appear as a ghost or spirit within Sandoku's own head and the two often talk to each other.
Unless your a friend or family member, approaching Sandoku could lead to a frightening encounter with Pampaku. Pampaku doesn't like his ghost form alot, but tolerates it as Sandoku's body does make a nice getaway when he wants to sleep or plan future mischief when Sandoku falls asleep. Unless you have specially trained eyesight, you might just see Sandoku talking to a tree or himself, which did lead to most avoiding him as they thought he was crazy when he was talking to Pampaku for comfort.

Pampaku can't take tf diapers into Sandoku's body as it would strain on him. This also shows that when Sandoku wears something, Pampaku ends up wearing it too. Sandoku is wearing the real FJorzek, while Pampaku is wearing a lookalike. His face can't be seen since Pampaku does like to hide surprise diaper tfs on Sandoku, but when Sandoku talks to Pampaku, he can see that Pampaku put him in a tf diaper.

Sandoku and Pampaku belong to Me.
