In 1989, Tommi Piper released the album Tommi Piper singt Alf, whose title Hallo Alf, hier ist Rhonda was placed in the German single charts for twelve weeks.
In the German version of Gremlin's Invasion, Sandra Bullock is voiced by her typical German dubbing voice Bettina Weiß.
The rides opened on June 3, 1991 in Australia and Germany, and the Australian ride closed in 2001 and was to be replaced by a Scooby-Doo-themed ride to coincide with the release of the new Scooby-Doo film.
In Germany, Gremlin Invasion was used for the Halloween Horror Festival as Terror Train from 1 October 2002 to October 2007. The ride's winding backdrops were perfect for the cast members dressed as monsters who could scare the passing guests.
Alf and Gizmo beat the Gremlins the same way they were beaten in Gremlins 2: The New Batch.
