Lenni is a character in the 2012 film Little Brother Big Trouble: A Christmas Adventure. He is the father of Jonni, the husband of Oona, the son-in-law of Grandpa and the step-father of Niko. At the end of the film Lenni and Oona have a daughter together, thus giving Niko and Jonni a half-sister. He was voiced by Riku Knihtila.
Lenni is an ordinary but warm-hearted single dad. After the tragic loss of his wife Lenni dedicated his life to raising Jonni and offering him all the love and care needed. Lenni is a bit shy when it comes to social relationships and he often tends to revert to his default small-talk position which means talking about the weather when he feels awkward and is having a hard time finding the right words.
