Great stuff. Love the feel of the work. It could clearly be something relatively frightening if you think about it (a big freaking object/creature/being) that comes out and steals your stuff but it's presented in a lighthearted way.
RE: limbo, just got back from a long weeken d in Dublin where I had time to ponder on this. I seem to have three options:
1. Base it on a person (young boy or girl) who gets sucked into Limbo and discovers what is there etc. etc.
2. Make Limbo a place inhabited by native characters and base the stories on what they get from the tubes (so to speak)
3. Base it around characters that have inhabited Limbo while keeping how they get there (just who is operating the tubes?) a mystery.
3. seems the most natural for me...if I choose 1 it would be a one off story and 2 gives up all sense of mystery.
Still undecided but I have modelled a few surreal characters just in case I go with 3...although I have to admit, this was always going to be my 'weird' project!
You could do both options 1 and 2 from the earlier post. The first Limbo story would have someone discover what is there as in option 1. What they would discover are the natives from option 2. Then you can continue with more stories using option 2.
