Imagine your favourite character filled to the brim. No place anymore, totally full. Still there's something this character can do! What could it be?
* b-word. Teetering on the brink and then having atoms rearranged: becoming rubbery pieces, or making a gory mess, or detonating into heating and lighting, or flooding the place, whatever, etc. etc. etc.
* flying. Very popular
* um... just having fun of being there? Staying inflated and doing nothing for all eternity - quite frequent
* talking. In many stories they gonna pop - and still muster an "OOOOH!" before they go off. If they do that, surely it's not too much trouble to smile and say "hiii!" ^_^
* thinking. If she can think “gonna pop! Gonna pop! Gonna pop!” surely she can think “okay, Pump; shut down”
* looking, hearing, tactile feeling (touch), etc. Eye motions can be tracked
* bouncing around (can surprise, distract, or even pop others)
* rolling around (still, some remains mobility…)
* … any ideas?
Oh, I thought this was if you actually inflated in the real world. Whoops.
