This is Dave. He's broken 
Dave has an elasticated tummy, which DS has stretched beyond its limits
Dave's stomach tone is now worse than mine, and we need help!
He's got some sort of retractable mechanism inside - when you stretch him out he should make a clicking sound, then when you let go he judders back to his original size - a bit like my little rotary tape measure I got from the haberdashery. I need to find a replacement mechanism for him but my google hasn't found anything because I don't know what to search for. I'm half minded to unpick him and have a look what's in there, but was reluctant to disembowel him before I know that I can get something to repair him with.
Does anyone have any ideas? What do you call elasticated retractable crocodile innards?
(Not a question I ever thought I would be asking...)
