Olli  Olli is a cartoon character and a stuffed toy and a drink. The character Olli was original created in 2004 by Dutch designer and film director Hein Mevissen and writer Diederiekje Bok as a character for a bottled mineral water. Olli was one of many characters used on the packages and posters of the bottled water brand and John's Phone. Olli was launched on a party of MTV In Rotterdam in 2004. In 2013 Olli was again part of a campaign. This time to save the Rotterdam Zoo Diergaarde Blijdorp. Olli is part of the Ollimania family which is the company that created and owns all characters. Olli became a national hype in the Netherlands from the launch in 2004. After the launch Olli became the symbol of Rotterdam and professional football club Feyenoord. On 10 September 2015, Ollimania and its creators Hein Mevissen and Diederiekje Bok donated a huge Olli statue to the Sophia Children's hospital in Rotterdam. They did this to give a smile to the little patients and parents in the hospital. This original big Olli is there to stay. The first two Ollimania books were launched in October 2014. 'Olli en het poepkanon' and 'Olli is een olifant'. Both books made it into the top 10 of best sold children books in the Netherlands. In June 2015 Ollimania published again two new books called 'Olli en de woestijndraak' and 'Olli op reis'. Hein Mevissen and Diederiekje Bok from design company John Doe designed Olli from the basic shape of a soccer ball. They believe the basic shape, size and character was part of Olli's success. This made Olli easily recognizable to audiences. Olli is drawn in a minimalist style, requiring only a few lines and one primary color. Olli was created in three sizes, one small size 4.7 in. one medium, size 11 in. and one big size 7.2 ft. There are two big Olli's. They are the elder version of small Olli. The Big Olli's is a special creature model made for several charities. One is a permanent hard plastic polyester statue at the Sophia Children's hospital and another one has a temporarily place at the Rotterdam Zoo. The big Olli that is used in the short film to save the Rotterdam ZOO is stored at a secret location according to the creators.
