However, there is never any need for the Adam Smith's timbers to shiver in trepidation - although Nikki Auld's sea-witch Octavia gives many a stout heart the quakes - because writer Alan McHugh and director Jonathan Stone are in full command of the show's cargo of romance, evil doing, snappy dancing and uproarious larks.
It is not only wee ones who gasp with delight when the little mermaid swims into view. Or should that be flies? Julie Heatherill's Marina stays elegantly suspended above the seabed until she sacrifices her beautiful singing voice for the legs that will carry her to true love.
