In Muppets Most Wanted, Constantine and Dominic Badguy found Thomas Blood's key inside Godfrey the Unknown's marble bust. In Madrid, Spain, the bust was kept in the Statue Room at the Prado Museum with 250 other statues. The two bad guys broke into the museum and smash the bust to get the key. Dominic said that, "no one knows what what Godfrey the Unknown looked like," while trying to find the right bust proved somewhat difficult for the pair, in which Constantine remarked, "of course not, he was second in command, so no one cared."
Godfrey's bust bears a strong resemblance to Dominic Badguy, according to Constantine.
