At a pinch, almost everyone would also know what "flower power" is.

The Shed Flower is a kind of curry comb (Striegel).

As the emphasis is on "your pony", we may assume that the product (produced in bright colours, as well) targets younger equestrians. - therefore "Striegelspaß"

The form and gentle function of a curry comb of this type makes it particularly suitable for use by children. Harder combs or shedding blades could easily injure the pony in inexperienced hands.

Some Wiki information about grooming combs:

Curry or Curry comb:

A tool made of rubber or plastic with short "teeth" on one side, that slides onto the hand of the groom. It is usually the first tool used in daily grooming. The horse is rubbed or "curried" to help loosen dirt, hair, and other detritus, plus stimulate the skin to produce natural oils. The curry comb is usually used in a circular motion to work loose embedded material. Curry combs are generally too harsh to be used on the legs or head, though varieties made of softer rubber are available.

Metal curry comb or Fitch curry comb:

The metal curry comb is not designed to use directly on a horse's coat as the metal teeth can damage the skin and hair. It is a curry comb made of several rows of short metal teeth, with a handle. They are primarily designed for use on show cattle, but are frequently used to clean horse grooming brushes by moving the brush across the metal curry comb teeth every few strokes.

Shedding blade:

In special weather conditions, a metal shedding blade with short, dull teeth is used to remove loose winter hair. A shedding blade is also useful for removing caked-on mud. However, grooming tools with metal teeth can split and dull the horse's hair coat and may irritate the skin, so must be used with appropriate care. Likewise, metal grooming tools used on sheep and show cattle may also be too harsh to use on a horse.
