Anagram Sitting balloons are three dimensional figures that set, without the use of helium. Each package comes with a straw for inflation. An air pump or inflator can also be used for inflation. Most Sitting balloons come with three separate balloons (the body and 2 legs). Inflate each balloon and interlock legs to the body. These balloons are available in different themes. Some themes include Halloween, Christmas, Easter, Valentine’s Day, Thanksgiving, graduation, and so much more.
