In the cannabis world, when people talk about a true “fairy tale,” they are often referring to the story of Mr. Soul (Rick Lomonaco) and Brothers Grimm Seeds. It is a story of mathematical precision, incredible luck, and a legendary genetic line that was later preserved by breeders such as Mosca Seeds when the original seemed close to disappearing forever.

1. The discovery of the century – The “Princess” saga

The story began in the mid-1990s inside an Amsterdam coffeeshop called Sensi Smile. Mr. Soul discovered two accidental seeds inside a pack of Jack Herer from Sensi Seeds.

After germinating them, he found an extraordinary mother plant that he named Princess.

Princess was a genetic anomaly. She delivered the electrifying, clear-headed high of a Sativa, yet flowered in only around 50 days. Her aroma was intensely tropical, dominated by pineapple and exotic fruit notes that seemed almost artificial.

Since Princess only existed as a clone, Brothers Grimm made it their mission to preserve this magic in stable seed form for growers around the world.

2. The mathematical revolution – Cubing

To stabilize Princess, Brothers Grimm used a breeding technique that later became famous as “Cubing”.

Without a suitable male counterpart, Princess was crossed with a male from Shiva Skunk. Over three generations, the resulting males were repeatedly backcrossed to the original Princess mother.

The result was the legendary Cinderella 99 (C99). It became one of the first Sativa-dominant strains that was easy to grow indoors like an Indica, while still delivering an intensely euphoric, energetic high.

3. The disappearance and the torchbearer – Mosca Seeds

In 2002, the cannabis world was shocked when Mr. Soul disappeared from the public scene following increasing legal pressure in the United States, particularly during Operation Pipe Dream.

Brothers Grimm Seeds shut down, original C99 seeds became rare, and prices exploded on the underground market.

At this point, Mosca Seeds, led by breeder Mosca Negro, stepped in to preserve the genetics. While Mr. Soul remained underground, Mosca recognized the immense value of Cinderella 99 and continued working with remaining original stock.

Mosca Seeds released their own C99 backcross lines and helped keep the legend alive for more than a decade. Many growers from the 2000s only experienced Cinderella 99 thanks to Mosca’s preservation work.

Mosca also selected exceptional phenotypes, including the famous Sonic Fly, while preserving the iconic pineapple terpene profile loved by Sativa enthusiasts worldwide.

4. The resurrection – The comeback in 2015

After more than 13 years of silence, Mr. Soul returned in 2015 and officially relaunched Brothers Grimm Seeds.

Over the years, he had secretly preserved many of his original “Holy Grail” genetics. His return marked a new era of collaboration and respect, because without preservation breeders such as Mosca Seeds, the Cinderella 99 line might have faded away forever.

Today, both seedbanks continue their work in different ways: Brothers Grimm refines the original vision, while Mosca Seeds integrates the genetics into modern award-winning hybrids.

Conclusion – A shared legacy

Brothers Grimm Seeds and Mosca Seeds are permanently linked through cannabis history.

While Mr. Soul was the architect who designed the blueprint, Mosca Negro became the guardian who ensured the structure would never collapse. Together, they preserved the legendary pineapple-fueled high of Cinderella 99 for generations of growers and Sativa lovers worldwide.
