happy as a clam
Blissfully at ease
Happy as a clam means perfectly content or thoroughly pleased.
The full expression is "happy as a clam at high tide"—when the water is high, clams are safe from diggers and can feed undisturbed.
The shortened form survives as an American idiom for carefree satisfaction: Leave him alone with his books and he's happy as a clam.
