I have a vague recollection of a film that I saw in the 80s. I was of children living somewhere snowy, maybe Canada (think it was an american film). People were going about on snow mobiles. The children found an unmanned/parked small UFO and went inside, were a bit scared but then ended up filling the floor of the small UFO with sweets by pressing something or activating something. Can anyone tell me what that was, it's been bugging me for a while.
Thanks, Matt
