OH MY GOD FURBIES WHY.
Furbies
Not only did Furbies contribute to the disintegration of the American child's grammatical development — "Me love you!" — but they also turned kids into worshippers of mechanical owl-like things with creepy eyes and creepy ears and oh God you had to stroke them all over.

Gooey Louie
In this game, you'd pull boogers out of Gooey Louie's nose, but one was a bad booger which would make Gooey Louie's brain pop out. True story.

Puppy Surprise
Basically, you get this pregnant dog and then you get to birth her puppies over and over again. Which was really not a great deal for the dog. Just when she thought it was over, you'd pop those pups back in and oh, great, knocked up again.
Quints
I'd like to think these sets of dolls introduced girls at an early age to the benefits of birth control.
