So im looking for a movie I think is from the 80s (maybe 90s) involving two aliens and a robot band (I think).
I remember seeing this movie as a kid during the 90s. The only thing I can remember where to alien creatures riding in a shopping cart in a mall. Outside of the mall the two alien creatures "collided" and fused with each other. And also there was a robot band (I think). I am sorry if this sounds kind of "druggy" or whatever but I have a very clear memory of this particular scene/scenes. I also remember the alien creatures looking somewhat like E.T (short, brownish).
Please tell me that this is not some kind of fever dream I had as a kid.
