Most Infocom games contained feelies: additional items related to the game enclosed in the package. Ballyhoo featured the following feelies:
* An "Official Souvenir Program" from The Traveling Circus That Time Forgot describing each of the featured acts and listing common circus slang
* A ticket to the circus
* A toy balloon imprinted with the circus' name and logo (blue was the most common color, although a few orange or black ones were also shipped)
* A trade card for "Dr. Nostrum's Extract", a fictitious patent medicine hailed as a "wondrous curative" containing 19% alcohol
Munrab, the name of the circus' owner, is "Barnum" spelled backwards.
The Lost Treasures of Infocom bundled 20 Infocom releases, including Ballyhoo. This package as shipped lacked some information necessary to complete the game; the final page of the souvenir program was omitted. This page was an ad for a classical music radio station; at one point in the game, the player must tune a radio to the frequency listed in the ad in order to proceed.
