When a donkey named Sylvester finds a magic pebble, his wish to escape a fearsome lion transforms him into a rock, leaving his parents to grapple with an unmovable mystery.
One rainy day, Sylvester Duncan, a donkey living with his parents in Oatsdale, is collecting pebbles, a hobby he enjoys. Walking along a path on Strawberry Hill, he finds a small, smooth, brilliant red pebble. Intrigued by its unusual color and sheen, he picks it up. He wishes it would stop raining, and the rain instantly stops, and the sun appears. Realizing the pebble's power, Sylvester decides to take it home to show his parents, excited by the good it could do.
On his way home, still on Strawberry Hill, Sylvester is suddenly confronted by a fierce, hungry lion. Terrified, Sylvester's first thought is to wish he were a rock to avoid being eaten. He clutches the magic pebble tightly and wishes, 'I wish I were a rock!' Instantly, his donkey body becomes a stationary, ordinary rock. The lion, confused by the sudden disappearance of the donkey, sniffs around the rock, puzzled, and eventually wanders away, leaving the rock-Sylvester alone and immobile.
As a rock, Sylvester is still conscious and can think, but he cannot move or speak. He quickly understands his mistake: the magic pebble, which was in his hoof, is now part of the rock, lying just beside him. He cannot pick it up, and therefore, he cannot make another wish to change himself back. Panic sets in as he realizes he is trapped, unable to communicate or reverse the magic. He lies there, a silent, unmoving stone, with the magic pebble tantalizingly out of reach.
Back at home, Mr. and Mrs. Duncan grow worried as night falls and Sylvester does not return. They search the house, call out his name, and eventually go outside, looking around Oatsdale. Their search continues for days, then weeks, and months. They consult police, put up 'missing' posters, and even travel to distant towns, but there is no sign of their son. Mrs. Duncan is sad, constantly weeping, and Mr. Duncan tries to comfort her, but they are both filled with sorrow over Sylvester's disappearance.
A year passes, and the seasons change, but the Duncans' grief for Sylvester never fades. They try to live normally, but their home is quiet and empty. Each day, Mrs. Duncan sighs, and Mr. Duncan tries to keep her spirits up, often without success. They continue their daily routines, but every activity reminds them of their missing son. Meanwhile, Sylvester, still a rock on Strawberry Hill, observes the changing seasons, feeling the sun, rain, and snow, but remaining a silent, helpless observer.
One beautiful May morning, a year after Sylvester's disappearance, Mr. Duncan suggests to Mrs. Duncan that they have a picnic. He thinks it might lift their spirits. Mrs. Duncan agrees, and they pack a lunch. They decide to go to Strawberry Hill, a place they enjoyed in happier times. Unbeknownst to them, they choose the very spot where Sylvester, now a rock, has been sitting for the past year. They spread their blanket near the familiar-looking rock, unaware of its true identity.
As Mr. and Mrs. Duncan enjoy their picnic, Mr. Duncan notices a small, shiny, red pebble lying next to the rock they are sitting on. He picks it up, admiring its beauty, and places it on top of the rock, remarking that it's 'a nice one' to Mrs. Duncan. This is, of course, the magic pebble that Sylvester used to transform himself. Sylvester, inside the rock, feels an intense surge of hope, knowing that his parents now have the key to his freedom, even if they are unaware.
After finishing their picnic, Mrs. Duncan, still feeling sad, says, 'I wish Sylvester were here with us. I wish this rock were Sylvester!' She says it with a wistful sigh, not truly believing in magic. At that very moment, because the magic pebble is resting on the rock, her wish is granted. There is a flash of light and a puff of smoke, and the rock transforms back into Sylvester, who tumbles off the blanket, alive and well, to the shock of his parents.
Mr. and Mrs. Duncan are initially stunned, unable to understand what just happened. Then, immense joy washes over them. They embrace Sylvester tightly, laughing and crying with relief and happiness. Sylvester, equally overjoyed, explains the entire story of finding the magic pebble, his transformation into a rock, and his year-long wait for rescue. His parents listen in amazement, barely believing his fantastic tale. The family is finally whole again, their long period of sorrow replaced with delight.
The reunited Duncan family packs up their picnic basket and heads home, their hearts full. They decide that the magic pebble, despite its power, is too dangerous to keep and use. They place it in a safe place on the mantelpiece, where it can be admired but never used again. Life in Oatsdale returns to normal, but with a new appreciation for family and the preciousness of everyday moments. Sylvester is back, happy and safe, and the family lives contentedly, changed by their experience but grateful for their reunion.

The story emphasizes the severe results of acting without thinking. Sylvester's immediate wish to become a rock, born of panic, leads to a year-long problem. His inability to change back shows how a hasty decision, even with good intentions (self-preservation), can trap one in an undesirable situation. This theme teaches young readers the importance of careful thought before action, especially when dealing with powerful forces.
“'I wish I were a rock!' he thought, and in less than an instant, he was. The magic pebble lay on the ground, right next to the rock he had become. 'Oh, dear,' he thought. 'I wish I hadn't done that.'”
The enduring love of Sylvester's parents is central to the story. Their deep sorrow, relentless search, and year-long mourning show the strength of their family bond. Mrs. Duncan's wistful wish, born of her longing for her son, ultimately breaks the spell. This shows how love, even unknowingly, can have a powerful magic, capable of overcoming difficult obstacles and bringing about miraculous reunions.
“'I wish Sylvester were here with us. I wish this rock were Sylvester!' she said to the rock, not knowing that it was Sylvester. And at that very instant, the wish was granted.”
The magic pebble represents unchecked power. While it can grant wishes and bring joy, it also carries great danger if misused, as shown by Sylvester's transformation. The story shows that power, even when seemingly good, requires caution and wisdom. The Duncans' decision to keep the pebble as a keepsake but never use it again reflects a mature understanding of its dual nature, prioritizing safety and simple happiness over magical capabilities.
“They had a good lesson. BUT, they never used the magic pebble again. It was too much for them to have, and they put it in a very safe place.”
Sylvester's year-long wait as a rock on Strawberry Hill shows patience and enduring hope. Despite his helplessness and the passage of seasons, he remains aware and, implicitly, hopeful for a solution. Similarly, his parents, while sad, never fully give up hope, continuing to mourn and remember him. The unexpected reunion reinforces the idea that even in the darkest times, hope can be rewarded, and patience can lead to a fortunate outcome.
“He was a rock. He couldn't move. He couldn't speak. He couldn't hear. All he could do was wish that he wasn't a rock, but that was no help. He was a rock. He stayed on Strawberry Hill.”
The central magical object that grants wishes.
The magic pebble is the primary plot device, serving as the source of all conflict and resolution. Its ability to grant any wish immediately drives the initial plot, leading to Sylvester's accidental transformation. Its presence (and absence) dictates Sylvester's fate. Later, its accidental proximity to Sylvester (as a rock) and Mrs. Duncan's wistful wish allow for the reversal of the magic, bringing the story to its happy conclusion. It represents both temptation and the potential for good or ill.
Sylvester's physical change from a donkey to a rock.
The transformation of Sylvester into a rock is the core conflict-generating device. It immediately creates an insurmountable barrier for the protagonist (immobility, inability to speak or interact) and sets in motion the parents' desperate search. This device allows for a prolonged period of suspense and highlights the profound consequences of a magical mistake. It also serves as a visual metaphor for being trapped or helpless, only to be reversed by a coincidental re-engagement with the magic.
The audience knows Sylvester is the rock, but his parents do not.
Dramatic irony is used effectively throughout the latter half of the story. The reader is aware that Sylvester is the rock on Strawberry Hill, while his parents are completely oblivious, even sitting on him during their picnic. This creates tension and anticipation, as the reader hopes for the parents to discover the truth. It makes Mrs. Duncan's casual wish for the rock to be Sylvester incredibly powerful and satisfying when it comes true, maximizing the emotional impact of the reunion.
The Duncans' accidental picnic location and the pebble's placement.
The resolution of Sylvester's predicament relies heavily on a series of coincidences. The Duncans choose to picnic on the exact hill, at the exact spot where Sylvester is a rock, a year later. Furthermore, Mr. Duncan casually places the magic pebble (which he finds nearby) directly on top of the rock (Sylvester). This chain of unlikely events, while convenient, serves to deliver the happy ending and provides a magical, rather than logical, solution to the seemingly impossible situation, typical of children's fantasy.
