A California mother is outraged after her 5-year-old son was given a Playmobil pirate ship set that she says includes a black slave wearing a neck shackle.

Ida Lockett of Sacramento said her son received the toy as a birthday gift. However, she noticed the toy's manual instructed assemblers to put a silver shackle -- which Lockett described as "a slave collar" -- around the neck of a figurine that resembles a black slave. The character is also dressed in ripped pants, a torn yellow shirt and no shoes. Plus, the ship itself included a dungeon.

"It's definitely racist," Lockett told CBS Sacramento. "It told my son to put a slave cuff around the black character's neck, and then to play with the toy."

"You cannot have this specific accessory and call it anything else," she said referring to the neck shackle. "It's a slave collar."

In response, Playmobil sent a statement to The Washington Post explaining that the toy was created to portray life on a 17th century pirate ship.

"If you look at the box, you can see that the pirate figure is clearly a crew member on the pirate ship and not a captive," the statement reads. "The figure was meant to represent a pirate who was a former slave in a historical context. It was not our intention to offend anyone in anyway."

However, Aimee Norman, the boy's aunt who purchased the set, wrote on the Playmobil USA Facebook page that she was "MORTIFIED to have recently bought" the pirate ship set for her nephew, "only to hear that when assembling it, they found that its assembly instructions indicate to add the neck cuff/shackle to the black character's neck."

"Would it be too much to ask for you to just create a regular old black pirate?" she wrote.

Norman added that slavery should not be taken lightly.

"Selling children's toys that are suggestive of slavery in play is obscene, even moreso [sic] given the marked absence of diversity in your entire toy line," she said.
