My Doublecross has long lost it's spark, but Grotusque and Repugnus still has theirs. I haven't attempted to crack em open to fix it as I dunno how.
Looks a bit difficult though Tets, coz the plastic pieces seem to be joined with tabs inside as well as screws and some gluing together not just your standard unscrew and the pieces cracks in half. So be careful if you wanna have a crack at it.
