If you want to take a trip to Paradise Estate or Dream Valley, get ready to ride: More than 25 years after Hasbro introduced the ultimate reason for pre-tween girls to jump up and down shrieking, "They are so cute!" a new TV venture is saddling up to put a 'My Little Pony' series into its stable.

Per the Hollywood Reporter, Hasbro Studios -- a collaboration between the legendary game and toy manufacturer and the Discovery Channel -- is betting on 'My Little Pony' for its first successful production. Presumably most of the colorful, valiant and courageous equines beloved by legions of girls (and adult collectors) would appear in the show, including Pinkie Pie, Toola-Roola, Rainbow Dash, Sweetie Belle the unicorn and Starsong, a pegasus.

The cast of Boston Legal is now moving to children's toys. This only seems like a joke, but it's not. William Shatner, James Spader and Candice Bergen are among the celebrities and artists who will be designing new versions of "My Little Pony", the toy from the 1980's which launched an animated television series and movie.

(UPDATE: Stacey Luchs, a spokeswoman for the show, said Thursday that Shatner and Spader were unaware of the venture and would not participate.)

The special ponies will be auctioned off by Hasbro as a charity fundraiser. Other pony-designing celebrities include LeAnn Rimes, Debbie Gibson and Danny Aiello. Artists designing ponies include illustrator Catalina Estrada from Spain, New York graffiti artist-turned-designer Claw Money and Japanese manga artist Junko Mizuno.

Still, it beats having to redesign Planet Unicorn.
