Lost in translation

In my parents' kitchen is a Halloween-themed bag of grapes. The packaging says something along the lines of, "no trick, just treat." And then, it says, "Aucune mauvaise surprise; rien que du plaisir." Really? That's the best you could do? (That translates to, "no unhappy surprise; only pleasure.") Which makes no sense. But whatever, laws are laws, I guess.
