I found the pic of the seal (La Foca)
Now all we need is a poster, made up to look like a missing child poster on a milk carton. The caption:
HAVE YOU SEEN THIS PERSON? LA FOCA WAS RUN OUT OF MEXICO, SPURNED BY THE USA, AND REJECTED BY NICARAGUA. LAST SEEN HEADING TOWARD EL SALVADOR. IF YOU SEE THIS PERSON, PLEASE CALL PHIL IMMEDIATELY (IF YOU CAN FIND HIM) SO HE CAN POST THE APPROPRIATE WARNINGS.
Oh no, the dead have risen and they're voting Republican
