seems Foxy and Bonnie are having a size feud mainly about how they got big

Bonnie thinks that Inflating like big squishy balloon is the best method because its faster and easier to get big and round then fattening up, that and its easier to go back to your normal size then working out

Foxy thinks getting nice and fat is better due to the fact you are always ready big and soft and eating the scraps that would normally get thrown out is better then letting it all go to waist

what do you guys think? Which is a better expansion method?
