Is there an ending after you get turned into a blob? Also, I know on other runs you were able to not be addicted to Dizzy Donuts by something special you could get from there, but when you are a blob, you can't get the addiction away. Maybe you can develop something where the tubes satisfy your cravings for dizzy's while you are in the facility?
When you are a blob at home, you are just stuck there at the moment and you can lose the weight.
If you are send to the facility, then you can grow to fill the room as the girls that you fatten, there is dialogue at blob stage 30, it is the same dialogue like other girls, but now you are the one being fattened up and your feeder is congratulated, instead of you.
