My favourite definition of luck is 'preparation meets opportunity'. For luck where there was no such preparation I prefer the term 'dumb luck'. Where luck potentially involves dolphins - even if tangentially - then I tend to err on the side of 'dolphin luck'. If there was no preparation involved with that scenario then it gains the appellation 'dumb dolphin luck'. If the dolphin in question was actually mentally impaired then it's 'dumb dolphin dumb luck'.
Why do I feel the need to tell the world this?
Because when I am in a haze of sleep deprived pain and the drugs to amend said pain ... this is the sort of mental process I go through.
