One Sardinium can be found in each Octo Canyon mission. Standard missions have a hidden Sardinium that the player must find, while each boss mission's Sardinium appears in front of the Zapfish after the boss is defeated. There is also one hidden Sardinium in each sector of Octo Canyon.
Collecting a Sardinium that has already been found once before will give the player five Power Eggs instead.
