Rölli-peikko ( Finnish for "Rölli the Troll") is a character from Finnish television portrayed by Allan "Allu" Tuppurainen. The character originally appeared in segments on the children's TV show Pikku Kakkonen on YLE's Channel 2 in 1986. Original episodes were produced until 2001 and older episodes have been seen in constant reruns on the program. In these segments Rölli would tell stories of his amazing adventures while often criticising and questioning public norm or the activities of people (especially humans).
Rölli has also appeared in two feature-length films. The first, made in 1991 and titled Rölli - hirmuisia kertomuksia ("Rölli - Terrible Stories") was much truer to the TV character, whereas the 2001 Rölli ja Metsänhenki ("Rölli and the Forest Spirit") was more of a traditional fantasy/ adventure film. Rölli has appeared in an animated film Röllin Sydän (Quest for a Heart) which appeared in Finnish movie theaters December 2007. This film was a co-production made in four countries. 1
A notable feature of the show and later the movies are the many songs sung as a part of the story. Consequently, Rölli has been the basis of many successful children's cassettes and CDs.
