"Cartoon Heroes" is the ninth single release by the Scandinavian dance-pop group Aqua overall, and the sixth UK release. It is the first from their second album Aquarius. The song was their first release anywhere for over eighteen months, due to the time spent touring the world, resting and recording the new album. Although regarded their best song ever by some, it failed to follow the success of earlier tracks such as "Barbie Girl", making #5 in the United Kingdom and achieving similar positions in other countries.
