The game contains a number of characters which resemble musical acts and other popular characters. The owners of a couple complained that Sierra had used them without permission. Toys R Us complained about a robot shop named "Droids R Us", which Sierra changed to "Droids B Us"; the remake adds a character which resembles the toy company's mascot Geoffrey Giraffe. Rock band ZZ Top complained that a band seen briefly on stage resembled them – despite this, they re-appear in certain versions of the VGA remake.
