It's not a secret that large breasts are considered an attractive trait in a woman. A large part of this could be seen as evolutionary-driven as larger breasts mean that a woman could feed children more. Of course, humans are controlled by much more than their mating instincts and thus tastes in ideal partners vary from person to person. Still, by effectively selective breeding, larger breasts seem to be becoming more common as well as beginning earlier in puberty.
That being said, there is too much of a good thing. Some women develop breasts far larger than average. It may seem like a boon, but several problems can arise from breasts being too big. For one thing, the woman's frame may not suited to carry breasts above a certain size and can cause considerable back ache among other problems. And while large breasts draw male interest, shape and firmness are also big factors. Distended breasts that look flabby or sag too much may be more likely to repel instead of attract.
When a woman's breasts have grown large enough to be considered macromastia or even gigantomastia, the usual solution is breast reduction surgery. But with the arrival of Animalia came new options. All Animalian women (and herms) are quite busty, the lowest average being D-cups. However, they also have fit bodies which are able to support their breasts better. And their breasts are typically to scale with the rest of their bodies.
This group of girls who came to Animalia for conversion aren't the first to macromastia and probably won't be the last. These girls are from East Asia where women are typically petite. What would be large and impressive on a European woman would be burdensome on them. In Japan, girls such as them may be seen as suffering from a gyuki's curse, though that isn't taken seriously these days. The girls had agreed to become larger species of Animalians to better match the size of their breasts. They were all in agreement that they wouldn't become any type of cattle out of concern that it may somehow make their breasts even bigger. However, the relatively smallest one in the group decided to do something different from the others.

The Boer goat is the largest breed of goat in the world, with males standing at an average height of about 3 feet. Unlike several breeds of goat, the Boer goat is raised mainly for meat. Much like the Belgian Blue, the Boer goat has a stocky, muscular body. Wu figured that if the cow Animalians of that breed could have proportionate breasts to go with their bodies and not be hampered by them, then becoming a Boer goat ought to give her the same body type.
The results were rather pleasing for her. She didn’t get very tall, but she was taller than before. But more importantly, her body was a model of caprine fitness and strength. Yes, she still has very large breasts, but they were a bit more proportionate to her new body and her enhanced muscles made them firmer and not as heavy. And Wu was planning to this new body to compete in the Year of the Sheep/Goat competition. She had less than two years to prepare for that, but that should be more than enough time.
Wu had been the smallest of her group in terms of height and breast size. And she still was as the others had become bigger Animalians. They included a horse, a rhino, a giraffe, and an orca. The last two had been the biggest of their group. Since their conversion, they have been competitive over not only who looked better, but could do more with their new bodies. While the orca obviously had the advantage in swimming and the giraffe had the edge with running, they did make for an interesting pair of gym rivals. It was a pity they hadn’t converted early enough to sign up for the IAC Bodybuilding competition. Though more experienced bodybuilders with more time to prepare would have obviously won, it would have been interesting to see which of the two would have scored higher.

There was also a conversion that was going on of a similar but more private manner. There was an older gentleman who had gone to Horizon Labs but wanted to be more discrete about it. The reason being due to his ailment, a painfully-swollen scrotum that was most likely caused by testicular cancer. This gentleman (who wished to remain anonymous) had suffered quite a bit from the discomfort his swollen balls had caused him. So much, that he preferred to become a non-mammalian so he would have internal testes and not have to deal with this sort of pain anymore. At the moment, he was considering lizards and crocodilians, but he may be open to a Dinotopian conversion.
