The closing credits run at a ridiculously fast speed, 13 seconds to show them all.
Steve: We just got a real fancy letter.
Steve: You sure are excellent fish-finders. Now let's go see if we can find some more fish. I mean clues.
Steve: Let me guess. Is it a picture of a fish?
Phaedrus: Yes! How did you know?
Steve: Whoops. Less is more - got to remember that.
The closing credits included "Special Thanks to our Intern: Alyse Hachay."
David Burger is credited as "Duke" David Burger. Joyce Raimando appears, but is not credited.
Beginning with this season, there's a new "Cast" section that credits the voice actors/actresses of major characters with the names of their characters. Unfortunately, at this point, it's a generic list that includes cast that didn't necessarily appear in the episode.
Mailtime Segment: As part of the art theme, Mailbox has a mural on him. The letter is also decorated and Steve comments on it being very fancy. In the letter, Joyce Raimando is with some kids at the Museum of Modern Art in New York. The kids observe a sculpture and try to figure out what the person capture in the sculpture was doing.
