Ok, i've now played Roach Motel about 20 times and Goop STILL hasn't spawned!
Any tips?
I've killed everything first and gone back to where he spawns, i've killed all the toxic archers to see if that works, I've even gone to him first.
So why don't he spawn for me?

My PL name is Citrasena - add me if you can help.
Thanks
