Otter Pops are a brand of frozen snacks sold in the United States. The product consists of a plastic tube filled with a fruit juice liquid, with some varieties containing 100% fruit juice. Although Otter Pops are a 'Frozen Treat', they are conveniently stored and sold at room temperature. After purchase, the consumer stores the pops in the freezer. When consuming an Otter Pop, one must first cut open one end of the plastic tube, and then eat it like a popsicle that has no stick. Otter Pops were introduced by National Pax in 1970, to rival Jel Sert's similar product, Fla-Vor-Ice. In 1996, Jel Sert acquired the rights to Otter Pops, as well. During the 2000s, Jel Sert modified the recipe for Otter Pops to add more fruit juice. The new formula equates to three grams of sugar and 15 calories in each one-ounce serving. The current Otter Pops contain 40 calories per 2 oz. serving. (1 pop) The company's manufacturing facilities are located in West Chicago, Illinois.
