Sisu was born on March 27th 1983 in Kolmården's Dolphinarium and is the daughter of Siru and Flip. When Sisu was nearly one year old, on February 25th 1984, her mother Siru passed away and instead of nursing Sisu had to begin to eat fish. Soon she ate 3-5 kilograms of fish each day and when she was only two years old she ate as much fish as the adult dolphins in the Dolphinarium; 7-8 kilograms each day. After the death of Sisu's mother Penelope took care of Sisu until Flip began to take care of her instead.
Sisu was the tomboy of the Dolphinarium and she enjoyed being with younger males, even if she was an adult herself. Unfortunately Sisu died when she was 22 years old, 2005, after a long time of disease.
