In Japan one can purchase inflatable love pillows or "dakimakura" that are printed with a life-size picture of a porn star or anime character. Other less common novelty love dolls include overweight, intersex, elderly and alien dolls, which are usable for pleasure but also tend to be given as gag gifts. Some inflatable dolls even have the form of children.
Cheaper sex dolls are inflatable, using air. These dolls, representing the lowest price-range (less than US $75), are usually made of welded vinyl and bear only a passing resemblance to actual people. They have an artificial and typically crudely designed vagina or penis, but due to their affordability many users are willing to overlook their shortcomings. They often burst at the seams after a few uses, although they are commonly given as gag gifts and therefore many may not be used at all. In Russia for some years the Bubble Baba Challenge humorously featured participants river rafting on blowup dolls as a matter of entertainment but in 2013 the race was cancelled on "health and safety" grounds.
