Your mistake will help others learn. It's an example that will show others what could happen. :]
No big deal, even the 'experts' can do things wrong.
I'm proud of you for coming on here and asking for help while admitting your mistake! A real life friend of mine refuses to take a cardboard box with duct tape on it out of her corn snake cage. Has two corns in a cage too.. sigh. She says she's taught me 'everything' I know about snakes too..
I didn't think about it, but olive oil sounds like a good plan. Good luck and I'm sure he'll be fine.
