You can get get a mix up occasionally with seed. I ordered a distinct variety last year and the seeds I received produced various shapes of courgette none of which matched the one I had ordered. I contacted the supplier and received the correct seeds by return.
I can't imagine you have poisonous fruit ( as you are still alive to tell the tale ) but it would certainly be worth contacting your supplier and explaining your problem .....might save others from a similar experience
