I've reached the "stables" area where a key ring with a teddy bear is fastened to a hobby horse against a fence.
I have pliers in inventory - and these are supposed to force open the key ring.
[I've checked this with the walkthrough.]
But although I've tried the pliers against separate every link of the keychain I cannot get an interaction. The pliers just fall back into inventory all the time.
Can anyone offer advice, please ??
