Lillo was the most popular character in the original Tilt Tv (1994) sketch series, and was therefore made the protagonist of the show. He was also the only character who remained consistently faithful to his original personality and character traits in his main version. In early episodes, the other 3 main puppets shared some similarities with their original versions, with Lorefio displaying some of his acid-witted humor, Makò's basketball obsession being occasionally addressed and some mean comments about Tina's haggish appearance being made, but all of this was eventually removed from the show as it progressed. By the second season, the Makò, Tina and Lorefio puppet models were all given one regular new form (among the others) as Lillo's moronic police assistants. The new puppet model for Lillo was also slightly changed and became his prime version for the other spin-offs (Lillo non speak English (1997), Gramma Tilt (1997), In corso d'opera (1996) and In viaggio nel tempo (1996)): his hair color went from the original carrot orange to a darker red, the freckles were removed and a mustache was added.
The second season started by recycling episodes of the previous one with the addition of a frame setting involving Lillo revisiting these past cases to instruct his new cadets. However, as the show progressed, the team started to create entirely new material to employ as Lillo's tales.
Played as part of the second and third edition of the TV container show Solletico (1994) where children used to call from home to provide the solution to the unsolved cases.
The frequent puns and arrows at the expense of Tina's unattractive physical appearance in the original Tilt Tv (1994) sketch series had proved somewhat controversial, so the character (as well as most of its new incarnations) was gradually reinvented into a head-turning seductress and was so described in promotional material for the series. Dania Cericola took on the role(s) of Tina from original voice actress Anna Bonel doing a more sensual voice in line with the re-imagining of the character.
