Good ideas, thank you! I'll release a small update soon that'll let you have more options when immobile, including streaming & using the auto feeder.
You're right that housebound blobdom is a bit bare bones. I'll definitely expand on it soon.
I also just noticed that you can't go beyond the first blob stage. I don't know if it works on the girls, but I know it doesn't for the player. The mechanism that results in you getting points for a weight stage in the Dizzy's facility isn't present at the player's home, so it never ticks over to stage 2 or beyond.
