Question Where did Riley find a plastic stake that looked exactly like a real one?

-Where did Riley find a plastic stake that looked exactly like a real one? (And in such short notice)
-And how did he get the plastic stake through Spike's chest anyway?

Probably any outdoors store or sporting goods store would have pretty butch stakes for camping. This is not your grandma's plastic 😉

This is one of those moments in the show that makes me cringe. Plastic wood grain? Maybe he found it in the Sunnydale novelty shop, a tourist gift store maybe.
