Why do some toys have faces or look like animals?

A while back, in an effort to cater to the "new" female audience, sex toy manufacturers started making toys that looked less like penises. Another reason is that Japanese sex toys are prohibited from looking like penises, so manufacturers in Japan make toys that look like animals. There has been a move back to more "realistic" toys but the market has grown so much that there is room, it seems, for all the different varieties.
