Cocoa Krispies, Choco Krispis, Choco Krispies, Coco Pops, or Choco Pops is a breakfast cereal produced by Kellogg's, coming both as a boxed cereal and as a snack bar with a 'dried milk' covered bottom. It is a cocoa flavored version of Rice Krispies. Containing a substance imitating milk chocolate, the cereal can turn milk "chocolatey."
The cereal was introduced in the United States in 1958. In 2003, the cereal was renamed Cocoa Rice Krispies, as Kellogg's endeavored to unite their Rice Krispies variations under a single marketing schema. In 2006, the name was changed back to Cocoa Krispies. Kellogg's has released variations of Cocoa Krispies such as Cocoa Krispies Cereal Straws, Cocoa Krispies Choconilla, and Chocos.
The cereal is known as Choco Krispis in Mexico, the Dominican Republic, El Salvador, Costa Rica, Honduras, Colombia, Guatemala, Panama, Venezuela, Ecuador, Peru, Bolivia, Brazil, Chile, Paraguay, Uruguay, and Argentina, and Choco Krispies in Portugal, Spain, Germany, Austria, and Switzerland.
It was introduced in the United Kingdom as Coco Pops in 1961, and is also known by that name in the Netherlands, Denmark, Nigeria, Bulgaria, Ghana, Malta, New Zealand, Republic of Ireland, Finland, Italy, Greece, Sweden, Belgium, South Africa, Kenya, Uganda, Ukraine, Botswana, Hong Kong, Lebanon, Australia, Turkey and Republic of Korea and as Choco Pops in France. Later in the 1960s, the name was changed to Coco Krispies, but subsequently reverted to Coco Pops.
The cereal was available in Canada for a time, but was discontinued at some point in the early 1990s. Instead, Kellogg's sells a variant called Rice Krispies Cocoa, which is simply Rice Krispies with a light chocolate flavor. Several spin off cereals using the "Coco Pops" name, such as Caramel Flavoured Coco Pops, Coco Pops Crunchers, Coco Chex, Coco Rocks, Coco Pops Straws, Coco Pops Moon & Stars, Coco Pops Choc-N-Roll and Coco Pops Croc Prints (shaped like Crafty Croc's feet) have also been released by Kellogg's in some countries.
Chocos were introduced in some countries as Coco Pops Mega Munchers. A chocolate flavor porridge variant had been available in the end of 2000s called Coco Pops Porridge, but didn't last long. Since 2014, they have been brought back.
In February 1998, the British arm of Kellogg's renamed the brand in the country Choco Krispies, so it would be similar to the way the product was branded in the rest of the world. However, sales quickly declined, and in the spring 1999, telephone and internet poll with over one million voters found that 92% of voters wanted the name changed back to Coco Pops.
Thus, Kellogg's reverted to the original name in May 1999. The advertising campaign for the poll featured newsreader Alastair Burnet and Screaming Lord Sutch as the returning officer in a town hall election setting.
Cocoa Krispies first appeared in the United States in 1958, represented by a monkey named Jose. He was reportedly replaced by Coco the Elephant in 1960 when Mexican-Americans complained about the ethnic stereotype. In 1963, the Hanna-Barbera character Snagglepuss took over as the mascot. Ogg the Caveman took over towards the end of 1967.
By the end of 1973, Tusk the Elephant became the mascot of the cereal, and he remained until the end of 1982, when Snap, Crackle and Pop (the mascots of Rice Krispies) replaced and retired Tusk the Elephant. In 1991, the mascot became Coco the Monkey. In 2001, Snap, Crackle, and Pop returned and they have remained the product's mascots to date.
The cereal was introduced in the United Kingdom under the "Coco Pops" name in 1961, with Mr. Jinks as the mascot. Later in the 1960s, Sweep (a dog hand puppet from the popular children's television programme The Sooty Show) became the mascot for Coco Pops.
In 1963, Coco the Monkey was introduced, and he remains the mascot in those countries where the cereal is known as Coco Pops, Choco Krispies, and Choco Pops. In recent years, the design of Coco has been refined to give him a younger look. Coco's friends are Shortie Giraffe, Randy Rhino, Alan Anteater, Heftie Hippo, Fanny Flamingo, Osmelda Ostrich, and Kylie Kangaroo, while Crafty Croc and the gorillas are his arch enemies.
In 1986, the cereal introduced the mascot Simmo. It became popular quickly, with a short stint on the face of the merchandise and packaging for Cocoa Krispies. The Simmo mascot featured on various materials for around about three months. Simmo also starred in an advert for the company in 1986, alongside a female companion who only appeared once named "Heapo", a cartoon hippopotamus.
More recent advertisements (2009) in the United Kingdom have opted away from using Coco and his friends opting for things such as dancing milkmen and astronauts. Coco is still present on the box of the cereal and at the end of the advertisement but is no longer the feature character. However, the cereal box of 2009 has Coco's head as the main feature, with the title 'Coco Pops' and the cereal bowl smaller and on the right of the box. Briefly Coco was seen as a real life chimp. As of 2011, Kellogg's decided to bring Coco and his friends as well as Croc back, under a new space age style campaign known as the "Coco Pops Promise".
In those countries where the cereal is known as "Choco Krispis," an elephant is the mascot. In 1986, Kelloggs named the elephant "Melvin". Recently, he has been called "Commando Melvin" due to commercials featuring him a space faring fighter and adventurer, note that this is due to a misunderstanding, as Commando Melvin in the commercials refers exclusively to the organization featured in them whose purpose is to defend the "forti calcio plus" a supposed ingredient in the cereal from aliens or other such villains.
In July 2014, in Mexico, due to concerns about the sugary and caloric contents of the cereal and the relation kids made with the friendly mascot, Melvin the elephant had a physical transformation from a traditional elephant body to an athletic body resembling a strong teenager while keeping the head of the mascot, the cereal too had a recipe transformation to add more vitamins and minerals in order to focus the product into a health is fun type of communication. 
In Australia, the mascot is Coco the Monkey.
Coco Pops received two stars out of five on the Australian Government's health star ratings.
Kellogg's was criticized by health authorities in the United States and consumer experts in October 2009, when it unveiled a description on its boxes of Cocoa Krispies cereal that stated "now helps support your child's immunity". Kellogg's responded that it didn't create the new copy to capitalize on the H1N1 virus concerns, but added "Kellogg developed this product in response to consumers expressing a need for more positive nutrition."
The FDA may yet rule on the Kellogg's claim and some observers deplored Kellogg's marketing tactic. Compared to all claims on cereal boxes, "This one belongs in the hall of fame," said Kelly Brownell, director of Yale University's Rudd Center for Food Policy and Obesity. "By their logic, you can spray vitamins on a pile of leaves, and it will boost immunity."
There is concern that advertisements featuring, for example, children in playgrounds target children. LCM bars of the type advertised contain 30% sugar which the advertisement failed to mention. Advertisements by bus stops feature, "Ever thought of Coco Pops after school?" and parents fear children will want Coco Pops instead of healthier foods. Official support by Kellogg's for an anti childhood obesity campaign is seen as hypocritical.
