Slightly Blighty is the only one of my robots that I'm not prepared to back, as after the axe motor proved too weak, a much lighter blade was fitted, which wasn't nearly as effective, only really good for hooking, but Mini Shifter looks too slippery for that.

As for the other battles, Levitator, Captain TriMangle and Nausea.

In answer to your question Jimlaad, Slighty Blighty and Scraptosaur are made of thick HIP (High Impact Polystyrene), which is basically strong plastic, I think the same stuff was used for Rameses II in Series 2. Braveheart Bumble is made of aluminium, I doubt any spinner is getting through.
