While we're on the subject of Looney junk food, the Brach's candy company did a few Looney Tunes candies in the late 1980s/early 1990s. Most notably were their tie-ins with Bugs' 50th birthday (such as this Christmas tin from 1989).
From 1989, here's a bag of Bugs Bunny and Friends "Mellowcreme Candies". I actually recall eating some of these once back in the day... but have no memories of what the things tasted like.
And from 1990, here's an advertisement for a weird promotion.
