Madballs — Vintage Rubber Toy (AmToy, 1985)

Madballs are the grotesque rubber balls made by AmToy, released from 1985 to 1987. Each character had a unique monstrous face — from Screamin' Meemie to Slobulus. The line was a huge hit in the 1980s and became an icon of the gross-out toy craze.

Original AmToy Madballs in good condition are sought after by collectors. A brief reissue appeared in 2007, but the 1980s originals are the most valuable — especially with their packaging.
