The Ground Rules
Both you and the raptor are tethered to the bunk bed with 7 foot chains
The chains are unbreakable and cannot be removed from the bunk bed
The bunk bed is light enough that you can drag it a little
You are free to run around the bed or get on the top bunk
Now try your luck ....
I could survive for 51 seconds chained to a bunk bed with a velociraptor
(from BB, the home of all good things even if, annoyingly, she could survive three seconds longer than me.)
