A spud on the dark side. That's how toy maker Hasbro Inc. is promoting its latest Mr. Potato Head figure, Darth Tater (search).

The toy spud will be available next month, ahead of the May release of "Star Wars: Episode III — Revenge of the Sith," the latest installment in that film series.

Darth Tater will come with a light saber, cape and helmet, in addition to the regular Mr. Potato Head (search) accessories such as eyes, mouth and nose.

The Pawtucket-based toy maker says children will be able to "have all kinds of mix n' match, Mr. Potato Head fun with this wacky spud dressed as the infamous 'Star Wars' villain, Darth Vader (search)."

The toy will retail for $7.99.

"Star Wars: Episode III," starring Ewan McGregor, Hayden Christensen and Natalie Portman (search), will open in theaters nationwide on May 19.
