It is thought that his escape plan was devised by Swordid-Fish, Pappi's partner in crime, and that Pappi could now be anywhere between Devil's Island and the deep blue sea.
Pappi was caught up in a net of crime since the early days of the underwater underworld, culminating in the salmonella poisonings of '51. He was finally caught by a police-dogfish working undercover and, after the trawl, sent to Devil's Island to await his sentence - the electric eel. The date for his punishment was never set - the eel having other fish to fry.
