Executive Producer Sean Hayes joins the show's cast and crew as they pull back the curtain on the secret world of fairytales in this behind-the-scenes sneak peek of Grimm.

The cast explain how the new drama series "Grimm" is inspired by the classic, and sometimes terrifying, Grimm's Fairy Tales.

Bud Wurstner shows up at the Spice Shop to meet Monroe and Rosalee, whom Nick Burkhardt recommended he see regarding his hair loss problem. Bud asks if Rosalee has a remedy for hair loss for his "friend", and satisfied with their answer, he excitedly leaves.

Rosalee employs the help of Monroe in making the hair regrowth formula.

Bud returns to thank Monroe and Rosalee for preparing the formula "for his friend". Rosalee also tries Monroe's "creative" baking, which involved making a dandelion-seaweed cookie.

Bud comes into Rosalee's shop panicking because his hair (and his friend's hair) is growing out of control.

Officers Wu and Franco question Bud at his repair shop to determine if he has witnessed anything out of the ordinary.

Realizing he is trapped and doesn't have his cell phone to call for help, Bud attempts a dangerous retrieval.

Bud calls Wu and Franco for help with the intention of freeing himself from his predicament. Unfortunately, all three become entangled.

When Bud, Wu, and Franco are trapped in a disconnected freezer, backup arrives in a surprising way.

Juliette and Rosalee throw a big spa party at Juliette's house and are surprised when Madison shows up to demonstrate the products.

The party continues at Juliette's house and things began to get really warm.

As the party gets warmer, a Juliette and Rosalee trap a strange visitor in the kitchen and realize exactly what is going on.

After determining what is going on, Juliette and Rosalee put their plan to correct the situation into action with surprising results.
