Just reposting MoldRush's post so it's easier to read/notice...and I don't recall the marker brand, either:
To the question of the green box, I'm thinking maybe another possibility is that the parody was based on a ballpoint pen rather than the felt tip marker real product shown? Note the banana in the Wacky has what looks like a metallic ballpoint. So maybe the green box is based on a pen product which was less prevalent than the markers? Just a wild guess.
Speaking of felt tip markers, does anyone remember the brand name of markers where they came in a box, in a range of colors, and the box had a cartoon drawing of a smiling face where the crescent-shaped open-mouth smile was die-cut to reveal the marker colors inside? We had those all the time as kids but for the life of me I can't remember the brand.
