"...Just One Of Them Big Whirlwinds."

Three children were seriously injured after heavy winds picked up a bounce house while they were inside, hurling the giant balloon hundreds of feet, KFox14.com reported.

Witnesses near El Paso, Texas, said the inflatable toy was in the front yard of a home when a heavy gust of wind tossed it across the street and into a nearby yard.

"We just heard a loud bang,” Anita Rodriguez, who helped rescue the children, told KFox14.com.

“We actually thought that the balloon had just collapsed, that it was in that backyard of that house. Come to find out that it wasn't.”

The three children who were inside the balloon at the time range from 2 to 7 years old, fire officials told the site. All three were taken to a hospital and treated for serious injuries.

"I thought it was only the balloon. I didn't see the little kids. Then I heard the little boys crying," Victor Echegoyn, the owner the backyard where the balloon landed, told KFox14.com.

The inflatable toy was tied to a fence with two nylon ropes before the accident, according to the site.

“It was anchored down right, you know, it was just one of them big whirlwinds," Chuck Oxford, a relative of the injured children, told KFox14.com.
