Antimony: Zhu Zhu Pets?

A consumer group contends the Zhu Zhu Pets toy is unsafe.
But the maker of the robotic Zhu Zhu Pets hamsters defended its product against a study by GoodGuide that said higher-than-allowed levels of the chemical antimony were found in the toy.
Antimony is like poisoning, right? I don't want my kids to play with Zhu Zhu Pets if this is right.
Are zhu zhu pets dangerous for children? Do they get inffected with antimony?

Mister Squiggles, the light-brown version of the zhu zhu pets hamsters, has unsafe levels of antimony, said Dara O'Rourke, co-founder of GoodGuide.
But the guy who makes them said:: "zhu zhu pets do not contain high levels of antimony in any way."

He explained:

"All our products are subjected to several levels of rigorous safety testing conducted by our own internal teams, as well as the world's leading independent quality assurance testing organization, and also by independent labs engaged by our retail partners," Russ Hornsby, CEO of Cepia, said in a written statement. "The results of every test prove that our products are in compliance with all government and industry safety standards."

Antimony is dangerous but zhu zhu pets contain a safe level of antimony that can't hurt children.
