This wasn’t the first time McDonald’s Happy Meals came in a shaped “box” other than the classic one that was part of many of our childhoods if you grew up in the 1980s, but the one that really embodies the spirit of Halloween was the Trick Or Treat Pails that they put out back in 1986, and repeated to do so through to the 1990s.
The concept was simple but brilliant: make the containers of the Happy Meals come in essentially smaller, bucket-shaped versions of those plastic Jack-O-Lantern patterned trick-or-treat buckets they sell every year. Mind you, they were probably more geared toward the toddler set (I happened to be within the “probably too old to be trick-or-treating” age at the time these came out), as they didn’t seem to hold a lot of candy to satisfy your average candy monger. But, they did come in handy as decorations and holding other items.
I’ve seen these listed on eBay for a significant amount, so the nostalgia value of these things exist. Personally, I can’t recall if my sister and I ever got one of these. Either way, it’s a nice bit of flashback material to those who recall these fondly.
