Out of the Silent Planet
Usually when the game releases new Eddie, they also release a short clip for the certain Eddie accompanied with music from the song from which he is created (for this Eddie it was ROTAM - see here). The game also released (a while ago) a character (not Eddie!) based on ROTAM (see here).
Or Blackbeard Eddie could be a special edition of Navigator Eddie.... this will be not a surprise, since the game already released some special editions Eddies and a lot of unnecessary Eddies too.
