A sling-shot, set of inflatable suits that kids can don and wear while crashing into each other and a hammer inspired by weapons in the movie “Warcraft” ranked among the 10 most hazardous toys on an annual list released on Tuesday by U.S. child safety advocates.

The group World Against Toys Causing Harm Inc released its “10 Worst Toys of 2016” at the start of the U.S. holiday shopping season, saying that it intends to call attention to playthings that may be more dangerous than parents realize.

In addition to toy weapons and other playthings that could encourage children to launch projectiles at or crash into one another, the list includes a large stuffed elephant that the group warns could inadvertently suffocate an infant if left in a crib and a toy puppy with a 31-inch (79 cm) leash that could pose a strangulation hazard.
