These things take time sometimes, so I don't know how often you want to keep generating something.
I'm not feeling so creative myself at the moment, but perhaps I can still offer some sort of what-if scenario...
You put Flubber in a real life scenario. What about your other characters in real life scenario's? Where might they find themselves normally? How would they react? What if they were somewhere foreign to them or in an area they wouldn't normally like?
You can either use more photo's and insert them, or perhaps generate ideas off of this?
