There is a bowl of peanuts in the Knitty Kitty Club. Tinkle won't let you take them, though.
Tinkle is keeping a keen watch on the peanut bowl.
He has not much to do. But he has one reaction... Did you visit the basement?
That switch near the stairs. If you pull it, it will return automatically.
Well, not really. If you pull it and go back up, you see Tinkle will pull another switch and turn the lights back on.
I would say Tinkle is occupied while he is going for the switch.
Pull the switch in the basement. Immediately go back up and reach for the bowl. You have to be fast and you can grab the big peanut before Tinkle returns.
