Okay so when you use the Lizard Minion items and lock them in your inventory will they still work against the Lizard Minion?

Yes, they definately still work. I got a few events the last day with locked trap/spray and got all the items :)

Yep, I got the Capture a Lizard Minion achievement just the other day and it was locked.

good. cause every time that little bugger comes around i miss him because i accidentaly placed the items either in my shop or vault.

Thank you!
