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.
