Tails: "You'd think stuff like that would be a problem, and under normal circumstances it would be. After all, the world isn't exactly designed for people standing over 8 feet tall or more. But we're very blessed, my job as a contractor for G.U.N. has made it so I can afford to take care of whatever needs Cream and Mocha may have. That's why I built this new house, right down to the appliances and plumbing. Everything was made with my girls in mind!"
Cream: "But how about the giant chao looking at us from outside though? Anyway, as for Mocha's clothes and shoes, Mom has that covered. She's been making custom clothes since I was a kid since I was a fast grower myself shortly after I turned 6 and Tails asked me to be his valentine all those years ago. She makes clothes so fast now she's practically started her own custom-made clothing line and turned it into a side business. As fast as Mocha outgrows clothes, Mom makes new ones even faster."
Mocha: "And Daddy always makes sure I have more than enough food to eat no matter how big I get! We go through three cartons of eggs every breakfast and Mommy and me both drink an entire gallon of milk every meal, it helps us to grow even faster after all! I'm very blessed to have a daddy who never lets me go hungry, I love him so much! And now he even makes sure that Orange has enough food to eat too! I'll have to feed him right after I finish my breakfast, which looks delicious as always!"
asked similar questions, asking the Prower family about how they adapt to Mocha's (and to a lesser extent, Cream's) ever increasing size. The honest truth, and they aren't trying to brag at all, is that money does solve a lot of problems. Tails built their new house with the girls' growth in mind, he just flies if there's something he can't reach normally. And as for food and clothes, they have all the resources they could ever need. So feeding Mocha isn't a problem, and neither is clothing her or any bathroom-related circumstances.
Thanks for the question! For anyone who has questions for Mocha or anyone else in the Mochaverse, feel free to ask and they'll answer! ^^
