Oompas, now discontinued, were candy produced under the Willy Wonka brand name. They were labeled as ‘Peanut Butter Oompas’.
The candy produced from 1971 to 1983 was similar to today's Reese's Pieces and peanut butter M&M's (though bigger). Under the candy coating was a candy disk of one-half peanut butter, and one-half chocolate. In 1980, they were briefly available in a chocolate and strawberry (instead of peanut butter) variety.
In 2001, Wonka, now a Nestlé subsidiary, revived the brand name for a chewy Skittles-like candy that came in a variety of fruit flavors: Green Apple, Cherry, Lemon, Orange, Grape, and Strawberry. These were simply labeled ‘Oompas’.
The UK version had a different, more eccentric flavour variety: jam doughnut, rhubarb and custard, snozzberry (mixed fruit), popcorn, caterpillar (cucumber) and mashed potato.
