On October 25, 1983, Pikku Kakkonen received its trademark logo featuring combination of different creatures forming a large "2". The Finnish illustrator Camilla Mickwitz designed and animated stop-motion opening and ending sequences for the children's program.
From November 7, 1994 onward, opening and ending sequences were updated with the computer animation. On December 23, 1997, the acoustic theme music used since the beginning was replaced with a newer, synthetic arrangement.
In 2014, the logo was simplified with different color details such as eyes and buttons of the boy. Despite this however, the previous 2009-2014 logo was used as basics for the additional 40th anniversary logo.
