It is an ordinary brochure mentioning a triple-decker Conhugo cruise liner, sunbathing, parcheesi, and ballroom dancing. It has a picture of a tropical paradise with a ocean and green trees in the background.
Squidward risked stealing Mr. What Zit Tooya's wallet and running a stop light to what he thinks is a "tropical getaway." After Squidward goes to jail, Mr. Krabs gives the brochure, and Squidward realizes the prize is only the brochure. The only episode the brochure is shown in is "Good Ol' Whatshisname."
