Jack B. Yeats wrote a series of toy theatre (also called paper theatre) plays. In "My Miniature Theatre" (The Collected Plays of Jack B. Yeats), he explains performing his plays each year during Christmastime to entertain the children of the valley where he lived.

His plays were birthed from the influence of Robert Louis Stevenson and from a nostalgia for a time when successful plays for actors were then adapted to toy theater. The sets, the characters, and an adaptation of the script were sold for one penny (in black and white) or two pence (in colour) so that children could recreate the play at home. Nevertheless, certain scenes from traditional theatre were difficult to adapt to toy theater. Therefore, Yeats, who created his own stories, chose to limit characters that did ‘almost nothing besides talking and walking majestically.’ He highlighted the importance of voice since each character had to be distinguishable by their tone and way of speaking. Regarding the creation of the set and the characters, Yeats glued his scenery to cardboard, using watercolors and Christmas garland as well as candles to provide lighting.

Mistreated by his aunt and his uncle since the death of his father, the farmer Timothy Coombewest decides to leave and seek his fortune. He asks Marjorie Morning to wait for him for a few years and to marry him upon his return.

He becomes a cabin boy on board the Linnet. Once at sea, Captain Chief, or Blackbeard the Second, tasks his crew with a new quest: he wants to find an emerald that was buried by Jamesee Henderson several years before. Coastal erosion should have exposed the precious stone, permitting ships to see it with a naked eye.

Eight years pass, and the emerald still remains lost. Colorado Maduro expresses his gratitude at the kindness of Timothy (Tim), who has not let him die of hunger while the captain has imprisoned him in the ship's hold. He confides in Tim that he found and stole the emerald a year before, but that his destiny is sealed: the one who steals this precious stone is cursed with a year left to live, and the one who receives it as a gift will be blessed with prosperity. The ship jets out towards the cliffs and sinks. In a grotto under the sea, Tim meets Davy Jones, who gives him back the precious gem.

Tim, now captain, navigates towards the direction of his hometown. From the shore, the inhabitants see the sails of his ship and prepare to welcome him and to celebrate his marriage to Marjorie.
