Toy safety advocacy group World Against Toys Causing Harm (WATCH) outlined the top ten "worst toys" of 2019, including a Nerf gun and a Yeti doll.

Purely mechanical auto-filling guns also showed up at 2018's Toy Fair and it's probably safe to bet that the feature is only going to become more widespread with time, no batteries required.

James Swarrtz, director of World Against Toys Causing Harm, talks about the dangers of the Power Rangers Electronic Cheetah Claw during a news conference in Boston, Tuesday, Nov. 19, 2019.

A Nerf gun and a Power Rangers electronic “Cheetah Claw” are among the toys deemed most unsafe for children during the 2019 holiday season, according to a watchdog group’s annual findings.
