Changing the Furby Dynamic

With the semester winding down, we're getting to the part of The Great Furby Project that involves reflection. First off, after spending all this time with this children's toy, in what way could it be drastically improved? Is there a realistic feature that Furbies could have that would drastically improve the overall experience for the user? 

I have an idea in mind, one that would dramatically improve the Furby and would be incredibly easy to add. However, this addition would destroy something that is very important to what makes a Furby a Furbuy. It would change our notion of what a Furby is and what is is capable of: we need to give the Furby a sleep switch.

I know this is a mildly crazy suggestion. Isn't the whole point of a Furby that it can be accidently woken up at any point and that you need to leave it alone as it spouts out annoying catchphrases before it falls asleep? I'll concede that giving the user control over putting the Furby to sleep changes how you interact with the Furby, but this will force Hasbro to actually put the emphasis on development on legitimate interactions with the Furby. 

What I mean is that the vast majority of the interactions I've had with the Furby have simply been trying to get it to sleep. The toy seems designed as simply having two modes: the sleep mode when you are trying to not wake it up, and the awake mode when you are trying to get it to sleep. The sleep button would take away this dynamic, and force the developers to come up with reasons for people to actually want to play with their Furby, instead of simply presenting options for how to get them to fall back asleep.
